Abstract

PURPOSE:To obtain the titled novel polyester, melt moldable, having excellent strength and elasticity with hardly any anisotropy of mechanical characteristics in molding and suitable as films and sheets, by copolymerizing plural structural units. CONSTITUTION:The aimed polyester obtained by, e.g., acylating (A) preferably 20-90mol.% p-hydroxybenzoic acid (derivative) to be structural units expressed by formula I with (B) preferably 0.1-40mol.% dicarboxylic acid (derivative) (e.g., terephthalic acid, etc.) to be structural units expressed by formula II and (C) preferably 0.1-40mol.% optically active diols to be structural units expressed by formula III, polycondensing the acylation product to provide an oligomer and copolymerizing the resultant oligomer with (D) preferably 5-50mol.% 6-hydroxy-2-naphthoic acid (derivative) to be structural units expressed by formula IV.
