Abstract

PURPOSE: A resin with improved stability to sunlight and weatherability, having 4,4'-diphenyldicarboxyl groups.
CONSTITUTION: A resin comprising a high-molecular weight substance having 4,4'-diphenyl-dicarboxyl groups of the formula, or a mixture of a low- or high- molecular weight substance having the groups and other high-molecular weight substances. The content of the structural units is preferably 0.01 mole or more per kg of the resin or its composition. A polyester obtained from a dicarboxylic acid containing 0.5 mol% or more of 4,4'-diphenyldicarboxylic acid and a dihydroxy compound, e.g. an alkylene glycol, may be cited as the resin. The polyester is prepared by reacting the compounds at 130W300°C in the presence of 0.01W0.5 wt.% based on the acid component of a catalyst, e.g. a metallic oxide, in an inert gas.
