Abstract: PURPOSE:To obtain a copolyester excellent in melt flow property and capable of providing high strength and high modulus molding, by reacting an acyloxyaromatic carboxylic acid with a specified polyethylene terephthalate copolymer and poly condensing the product. CONSTITUTION:90-30mol% acyloxyaromatic carboxylic acid is reacted and polycondensed with 10-70mol% polyethylene terephthalated copolymer consisting of 40-80mol% polyethylene 4,4'-diphenyldicarboxylate units and 60-20mol% polyethylene terephthalated units. As the acyloxyaromatic carboxylic acid, p- acetoxybenzoic acid is particularly preferred. When the amount of an acyloxyaromatic carboxylic acid used is below 30mol% or above 80mol%, the copolyester finally produced does not have sufficient strength or modulus, which is not desirable.

Abstract: PURPOSE:To provide the titled compsn. producing molding products with excellent mechanical and thermal properties, anisotropy and appearance, prepared by adding a copolymer of alpha-olefin and alpha,beta-unsatd. acid glycidyl ester, to a specified copolyester. CONSTITUTION:The compsn. is prepared by adding 0.5-30pts.wt. olefinic copolymer consisting of alpha-olefin and alpha,beta-unsatd. acid glycidyl ester to 100pts.wt. copolyester consisting of 20-50mol% polyethylene terephalate unit and/or polyethylene isophtalate unit and 80-50mol% polyethylene 4,4'-diphenyldicarboxylate unit. When the amount of the olefinic copolymer is less than 0.5pts.wt., molding products with sufficient impact resistance and anisotropy and unobtainable and when it exceeds 30pts.wt., elastic modulus and thermal deformation point of the molding are lowered.

Abstract: PURPOSE:A polyester copolymer containing diphenyldicarboxylic acid is melt spun under specific conditions into fiber and drawn to produce the titled fiber suitably used as an industiral material, becuase of its high Young's modulus, high strength and elongation. CONSTITUTION:A polyester copolymer that is made from (A) the dicarboxylic acid component consisting of 45-75mol% 4,4'-diphenyldicarboxylic acid and of 45-75mol% terephthalic acid and (B) the diol component mainly consisting of ethylene glycol, thus having an intrinsic viscosity of 0.5-1.8, is melt spun, passed through the heating chimney right under the spinneret and/or through a cooling medium to adjust the optical birefringence of the spun yarn to less than 40X10 . Then, the resultant yarn is drawn to give the objective fiber with an optical birefringence of 250-400X10 . USE:Tire cord or conveyor belt.
