Definitions

  • This invention concerns poly-p-phenylenes which have perfluoroalkoxy and perfluoroalkyl substituents, their copolymers and the precursors to these polymers, including the perfluoroalkoxy- and perfluoroalkyl- substituted hydroquinones and triflate derivatives, and the corresponding biphenyl systems.
  • Polymers produced herein are useful as membranes, coatings, fibers and articles .
  • Polyphenylenes are highly rod-like materials and are therefore likely to give films with low in-plane CTE.
  • Typical polyphenylenes are highly insoluble, intractable materials and therefore extremely difficult to process into useful products. Thus, it would be useful to develop materials that retain the low CTE but have better processability characteristics.
  • the polymers and copolymers of the present invention melt without decomposition and show good processibility because of their solubility in selected polar organic solvents (e.g., THF) . This allows the casting of films and other shaped articles.
  • copolymerization with appropriate flexibilizing comonomers could result in improved elongation of these highly rod-like homopolymers while maintaining, to a large extent, the other desirable properties of the backbone.
  • This invention also affords a soluble polymer without the loss of the desired rigidity or an increase in the dielectric constant.
  • Rehahn, et al. Makromol . Chem. 1-21, p. 1991-2003 (1990) and Tour, et al., J. Amer. Chem. Soc. 113., 2309- 2311, (1991)) disclose that the solubility of p-linked arylenes can be increased by the presence of either some m-linkages in the chain or long alkyl chains attached to the phenyl rings. However, excessive amounts of such linkages or chains may result in the loss of the desirable rigid-rod properties.
  • Marrocco, et al. U.S. Pat. No. 5,227,457 disclose that increasing the solubility of rigid rod polymers by attaching either groups with molecular weights greater than 300, or between 15 and 300.
  • this patent does not teach that the perfluoroalkyl and perfluoroalkoxy are preferred as solubility-increasing substituents, and does not exemplify these substituents.
  • This invention concerns a polyphenylene, comprising repeat units with the formula
  • B is independently -OC r F 2r+ ⁇ or -C q F 2q+1 , where r is 1, 2, 3 or 4 and q is 1, 2, 3 or 4; wherein the total number of repeat units is at least about 10 and provided that (I) is at least about 50 mole percent of said repeat units .
  • the invention also concerns a compound of the structure:
  • Y is independently selected from the group consisting of H and -S0 2 X;
  • X is selected from the group consisting of OH, alkyl, fluoroalkyl, aryl, Br, Cl, F and I; and each D is independently -OC r F 2r+ ⁇ or -C q F 2q+1 , wherein r is 1, 2, 3 or 4 and q is 2, 3 or 4.
  • r is 1.
  • X be selected from the group consisting of -CH3, -CF3, phenyl and 4-methylphenylene.
  • the invention concerns a compound of the structure
  • Q is selected from the group consisting of OH, OS0 2 X, Cl, Br and F;
  • X is selected from the group consisting of OH, alkyl, fluoroalkyl, aryl, Br, Cl, F and 1/ and each D is independently -OC r F 2r+1 or -C q F 2q+1 , wherein r is 1, 2, 3 or 4 and q is 2, 3 or .
  • r is 1.
  • X be selected from the group consisting of -CH3, -CF3, phenyl, 4-methylphenylene and 4-fluorophenylene.
  • Incorporation of fluorinated groups onto the backbone of poly-p-phenylenes is a useful way of not only obtaining the desirable physical properties, such as low CTE, low moisture absorption and low dielectric constant, but also improving the solubility and thereby the processibility of polyphenylenes.
  • Applications for such materials include membranes, encapsulated, coated or shaped articles, and fibers.
  • the fluorinated diols and their derivatives are useful as monomers for making these polyphenylenes or copolymers containing these units.
  • the substituted poly-p-phenylenes may be made at acceptable costs; longer chains and therefore more fluorine would make the final polymers prohibitive in cost.
  • poly-p-phenylenes with hexyl or longer chains as substituents are completely soluble, whereas substituents of a chain length shorter than butyl are insoluble.
  • the methoxy substituted poly-p-phenylene is also insoluble in THF, DMSO, CHC1 3 and DMAc.
  • the polyphenylene of the present invention may contain 1, 3-phenylene linkages provided that the percentage of 1, 3-phenylene linkages does not exceed about 20% of the total number of 1,4 plus 1,3 linkages.
  • Polyphenylene copolymers may also be made, provided that the resulting polymer contains at least 50 mole % of repeat unit I.
  • polyphenylene copolymers may be made containing repeat unit I together with repeat units consisting of 1, -phenylene, 2-methyl-l, -phenylene, 2- (4-fluorobenzoyl) -1, 4- phenylene, 2, 5-bis-trifluoromethyl-l, -phenylene, 2- alkylcarboxyl-1, -phenylene, wherein the alkyl group contains from 1 to 20 carbon atoms, 2, 6-naphthylenyl, and -PhCOPh-.
  • preferred co-monomers for the poly-p- phenylenes can be any para oriented dihalo (preferably chloride), or dihydroxy aromatic monomer.
  • One class of these is with single or C-C connected benzene rings. Examples of these are 4, 4 '-dihydroxy (or dichloro) biphenyl, p-dichlorobenzene, hydroquinone, 4,4'- dihydroxy (or dichloro) p-terphenyl or p-quaterphenyl.
  • Such materials could also be substituted on one or more aromatic rings, for example, phenylhydroquinone and substituted phenyl hydroquinone.
  • Fused aromatic systems are also possible e.g., dihydroxy (dichloro) naphthalene (with 1,4 or 1,5 or 2,6 orientation preferred) .
  • Comonomers can be used up to a point where the resulting copolymer is no longer soluble or otherwise processible (e.g., melt) .
  • Similar compounds but with meta substitution could also be used in relatively small amounts without substantially detracting from the beneficial properties of the rod-like backbone.
  • Examples of such monomers are resorcinol, m-dichlorobenzene, dichloro- or dihydroxy-m-terphenyl, 3, 3 ' -dihydroxy (or dichloro) iphenyl . These monomers could be used up to the point where the properties of the rod-like backbone are adversely affected, e.g., lower modulus and strength, high thermal expansion coefficient.
  • Other potential comonomers are those with connecting groups between aromatic rings.
  • Examples of such monomers which substantially maintain a rod-like backbone would be , 4 '-dihydroxy (or dichloro) phenyl benzamide or , 4 '-dihydroxy (or dichloro) phenyl benzoate.
  • Examples of such monomers are 4, 4 '-dihydroxy (or dichloro) diphenyl sulfone, 4, 4 '-dihdroxy (or dichloro) -2, 2-diphenyl hexa fluoropropane, Bisphenol A, 4, 4 '-dihydroxydiphenyl- ether, etc. plus other isomers and 4, 4 '-bis (4-hydroxy- phenoxy) diphenyl sulfone.
  • Such groups should normally be chosen as to not seriously impact the high thermal stability of the polymer.
  • linking groups detract from the rod-like character of the backbone because of their non-linear nature, however, in some of these cases their isomers may not due to fact that they have highly rod-like conformations or crankshaft structures .
  • monomers 3, 4 ' -dihydroxy (or dichloro) benzophenone and 3,4'- dihydroxy (or dichloro) diphenylether.
  • Imide or other heterocyclic (e.g., benzoxazole) linking groups can also be employed, however, these will increase the polarity of the backbone.
  • a wide range of copolymers is possible.
  • these comonomers allow rigid, rod-like orientation to be maintained so as to maintain the desired properties.
  • a small amount of flexibilizing or kinking linkages may be acceptable or even desirable for optimum polymer properties.
  • the monomers, the substituents they contain, and the linking groups be chosen and used at levels so as to not seriously detract from the thermal stability, rod-like character, or, especially for electronics applications, increase in the polarity of the system (which may increase dielectric constant and/or moisture absorption) .
  • Copolymers of the present invention illustrated in Examples 17-33, are soluble in contrast to the copolymers of comparative Examples C-F.
  • the fluorinated hydroquinones of the present invention may be prepared from the corresponding 3- (OC r F2 r + ⁇ )phenols or 3- (CqF2q+ ⁇ )phenols by an Elb reaction employing potassium persulfate as described by Feiring and Sheppard, J. Org. Chem., vol. 40, 2543 (1975) .
