Abstract

PURPOSE: To provide a highly elastic modified polyester which has a good toughness and heat resistance by adding a specified amount of aromatic dihydroxy compounds to polyalkylene terephthalate and melting it by heating under a reduced pressure or in an inert gas stream.
CONSTITUTION: At least one aromatic dihydroxy compound which is selected from formulas I and II, wherein Ar is aryl and R is H or 1W10C alkyl, is added to polyalkylene terephthalates which are composed of terephthalic acid or corresponding derivatives and diol in a molar ratio of aromatic dihydroxy compound to terephthalic acid component of 1:100W50:100. This mixture is melted by heating in the presence of a proper catalyst and diol component of polyester is transesterified with the aromatic dihydroxy compound under a reduced pressure or in an inert gas stream, and the glycol component is distilled from the reaction system.
