Abstract: PURPOSE:An expanded resin molding having mechanical properties excellent in isotropy, prepared by expansion-molding an aromatic polycondensate showing optical anisotropy in a molten state. CONSTITUTION:An expanded resin molding, cell content of 5-75vol%, prepared by expansion-molding an aromatic polycondensate showing optical anisotropy in a molten state, e.g., p-hydroxybenzoic acid type fully aromatic polyester consisting of p-hydroxybenzonic acid and 6-hydroxy-2-naphthoic acid. Imparting of a cell structure to a crystalline polymer molding allows the polymer molecular chains to take a structure in which the chains are highly oriented along the surfaces of cells and makes it possible to obtain mechanical properties excellent in isotropy because of the effect of three-dimensional orientation.

Abstract: PURPOSE:To efficiently obtain a highly rigid, highly heat-resistant polyester, by resterifying ethylene glycol with a dicarboxylic acid mixture containing diphenyl- 4,4'-dicarboxylic acid under specified conditions and then polycondensing the reaction mixture. CONSTITUTION:Into an esterification apparatus are introduced (A) ethylene glycol and (B) a mixture consisting of 40-80mol% diphenyl-4,4'-dicarboxylic acid and 60-20mol% other dicarboxylic acids, in a mol ratio of (A)/(B) of 1.1-2.5:1. Then, the esterification reaction is started at 230-270 deg.C and at 0.5-2.5kg/cm g. When the degree of esterification reaches 20-60%, the pressure is gradually released, and the esterification is brought to completion at normal or reduced pressure. Then, titled polyester is obtained by subjecting the esterification product to polycondensation. EFFECT:It is possible to obtain a polyester which is excellent in m.p., crystallization characteristics, melt moldability, and is useful in the production of fibers, films, molded products, etc.
