Abstract
PURPOSE: To prepare a polyester useful as fibers and films, and giving excellent heat resistance, chemical resistance and dimensional stability on crosslinking treatment, by copolymerizing a specific compound having unsaturated bonds.
CONSTITUTION: An aromatic dicarboxylic acid (derivative), e.g. teraphthalic acid, etc., a glycol, e.g. ethylene glycol, etc., and a compound (derivative) expressed by the formula (R1 and R2 are H, etc.; A is divalent organic group; m+n=1; l is 0 or 1) (e.g. p-hydroxycinnamic acid, etc.), (0.01-50 mole% on the basis of the acid component) are copolymerized. Crosslinking treatment is carried out after drawing, by one of the following processes: (A) heating in air at 150°C to the melting point, (B) irradiating with ultraviolet ray, (C) impregnating with a peroxide (e.g. t- butylperbenzoate, etc.), thereafter thermally treating or irradiating with ultraviolet ray, and (D) irradiating with electron rays, etc.
