Abstract

PURPOSE: The titled elastomer, prepared by copolymerizing a dicarboxylic acid mixture with a diol mixture and a polyalkylene ether glycol of specific molecular weight, and having improved mechanical strength and transparency.
CONSTITUTION: One mole dicarboxylic acid mixture of 50W100mol% terephthalic acid with 0W50mol% isophthalic aicd is mixed with 1.1W2.0mol diol mixture consisting of 5W95mol% 2-methyl-1,3-propanediol and 5W95mol% tetramethylene glycol and 0.002W0.8wt% based on the total copolymer, catalyst, e.g. tetramethoxytitanium, and the ester interchange reaction is carried out in a nitrogen stream. A polyalkylene glycol ether glycol having a number-average molecular weight of 500W3,000 in an amount of 5W50wt% expressed in terms of phthalate based on the total copolyem, copolymer is added thereto and polycondensed to give the aimed elastomer.
USE: Molding and film materials, for industrial, food, medical, automotive parts, electrical, fibrous materials, etc.
