Definitions

  • the acid components may be formed by using an acid and/or an ester forming derivative , particularly a lower alkyl ester in the production reaction of the ethylene-2 , 6-naphthalene dicarboxylate polymer.
  • Preferred examples of the lower alkyl ester include dimethyl esters, diethyl esters and dipropyl esters. Out of these, dimethyl esters are preferred.
  • the hollow molded product made from the ethylene-2 , 6-naphthalene dicarboxylate polymer has a color b value ( Col-b value ) of 5 or less .
  • this b value is larger than 5, the hollow molded product deteriorates in color, thereby reducing the product value thereof .
  • the polymer used in the second hollow molded product is preferably obtained using an antimony compound or germanium compound as a polymerization catalyst.
  • the preform molding of the step ( 2 ) and the blow molding of the step (3) are known per se and known methods are employed.
  • the third hollow molded product of the present invention is made from a polyester composition which comprises 0.01 to 5.0 wt% of a specific ultraviolet absorber which is the same as the ultraviolet absorber contained in the first hollow molded product and 10 to 2,000 ppm of a specific pigment which is the same as the pigment contained in the second hollow molded product.
  • the barrel portion of the third hollow molded product has a birefringence factor
  • All of the above hollow molded products may contain various additives such as a phenolic, organic sulfur-based or phosphite-based antioxidant, benzotriazole, triazine, cyanoacrylate, benzooxazinone or benzophenone ultraviolet absorber, antistatic agent and the like as required.
  • additives such as a phenolic, organic sulfur-based or phosphite-based antioxidant, benzotriazole, triazine, cyanoacrylate, benzooxazinone or benzophenone ultraviolet absorber, antistatic agent and the like as required.
  • the bottle is washed with an alkali at 85° C for 10 minutes. After the above treatment was repeated 15 times, the physical properties of the bottles of Examples and Comparative Examples were obtained.
  • reaction product was polycondensed at 295° C and a high degree of vacuum to obtain an ethylene- 2 , 6-naphthalene dicarboxylate prepolymer having an intrinsic viscosity of 0.50.
  • This prepolymer was further solid-phase polymerized at 230° C for a residence time of 15 hours to obtain an ethylene-2 , 6-naphthalene dicarboxylate polymer for bottles having an intrinsic viscosity of 0.65.
  • Bottles were produced in the same manner as in Example 13 except that the above ethylene-2 , 6-naphthalene dicarboxylate polymer for bottles and the pigment (1) used in Example 13 were blended in a weight ratio shown in Table 4. The physical properties of these bottles are shown in Table 4.
