Definitions
- the present invention relates to a composition of unsaturated polymers with recurring structural elements, which contains a strained cycloalkenyl radical bonded via a divalent bridging group, and a one-component catalyst for thermally or by actinic radiation-induced metathesis polymerization; a method of polymerizing the composition; materials and moldings made of the crosslinked polymers coated with the composition or the polymerized composition; and crosslinkable polymers.
- reaction injection molding processes Another disadvantage is the strong heating of the reaction mixture by the heat of reaction, which places very high technical demands on a controlled reaction temperature. Compliance with a polymer specification is therefore difficult.
- WO 93/13171 describes air- and water-stable one-component and two-component catalysts based on molybdenum and tungsten compounds containing carbonyl groups as well as ruthenium and osmium compounds with at least one polyene ligand for thermal metathesis polymerization and a photoactivated metathesis polymerization of strained cycloolefins, especially norbornene described.
- Other polycyclic - especially uncondensed polycyclic cycloolefins are not mentioned.
- the one-component catalysts used for the ruthenium compounds namely [Ru (Cumen) Cl 2 ] 2 and [(C 6 H 6 ) Ru (CH 3 CN) 2 Cl] + PF 6 - can indeed be activated by UV radiation; the storage stability of the compositions with norbornene, however, are completely inadequate. These catalysts are unable to adequately replace the known two-component catalysts.
- Petasis and Fu describe the thermal ring-opening metathesis polymerization of norbornene using biscyclopentadienyl-bis (trimethylsilyl) methyl-titanium (IV) as a thermally active catalyst. Other cycloolefins for metathesis polymerization are not mentioned.
- polymers with strained cycloalkenyl radicals bonded to a polymer backbone via bridge groups are particularly suitable for the production of crosslinked polymers under the action of particularly one-component catalysts.
- the compositions of crosslinkable polymer and catalyst are stable in storage and, depending on the catalysts used, are even insensitive to air and oxygen, which allows processing without special protective measures. The processing is simple and the processing options are diverse, since no special precautions have to be taken due to an excessive reactivity.
- the polymers are suitable both for the production of solid moldings and coatings with particularly high adhesive strengths.
- the polymers can also be used to produce images by means of irradiation under a photomask and subsequent development of the unexposed Proportions can be used with a suitable solvent.
- a first object of the invention is a composition containing (a) catalytic amounts of a one-component catalyst for metathesis polymerization and (b) at least one polymer with recurring structural elements which contain a strained cycloalkenyl radical bonded via a bivalent bridging group, alone or in a mixture with structural elements of strained cycloolefins.

- an irradiation time can mean up to 60 seconds, preferably 5 to 60 seconds and particularly preferably 10 to 40 seconds.
- a longer irradiation time is chosen, for example, if the polymerization is predominantly carried out under irradiation and the final polymerization is only to be ended by post-annealing.
- a very special and surprising advantage of the process according to the invention is that the one-component catalysts used act as thermal catalysts after the irradiation. This gives rise to the possibility of polymerization to continue after a short irradiation time by adding heat, which offers economic and technical advantages in various areas of the production of moldings or coatings.
