Abstract
PURPOSE: To obtain the title molded product with excellent mechanical properties, heat resistance, and elastic recovery, etc., by irradiating a γ-ray to a molded product of a linear polyester copolymer prepared from specific acid component and dial component to effect crosslinking.
CONSTITUTION: A γ-ray is irradiated, pref. under reduced pressure or inert atmosphere, to a molded product of a polyester copolymer composed of (A) an acid component consisting chiefly of (a) an aromatic dicarboxylic acid such as terephthalic acid, naphthalene dicarboxylic acid and (b) an aliphatic dicarboxylic acid such as succinic acid, sebacic acid, or an aliphatic oxycarboxylic acid such as ε- oxycaproic acid and (B) a glycol component consisting mainly of an aliphatic glycol such as ethylene glycol, tetramethylene glycol and, if required, containing an aliphatic unsaturated group-carrying compound, thus giving the objective melded product.
