Abstract

PURPOSE:To obtain the titled polyester, having excellent melt moldability and heat resistance and capable of providing molded products having high whiteness, by copolymerizing plural recurring structural units. CONSTITUTION:(A) A compound, such as p-hydroxybenzoic acid, capable of providing structural units expressed by formula I (groups Ar1 contain 50-100mol.% groups expressed by formula II) in an amount of 30-80mol.% is blended with (B) 10-35mol.% 4,4'-dihydroxydiphenyl (derivative) capable of providing structural units expressed by formula III and (C) 10-35mol.% compound, such as 1,1,3-trimethyl-3-phenyl-indane-4',5-dicarboxylic acid, capable of providing structural units expressed by formula IV (groups Ar2 contain 50-100mol.% groups expressed by formula V) and polycondensation reaction is then carried out, e.g. at 250-390 deg.C, to afford the aimed polyester.
