Abstract
PURPOSE: To improve the heat and chemical resistance of a molded article effectively without degrading the essential property of the elastomer, by crosslinking a molded article of a polyester elastomer impregnated with a polyallyl compound and a reaction initiator.
CONSTITUTION: (A) A molded elastomeric article of a block copolyester consisting of (I) an acid component consisting mainly of an aromatic dicarboxylic acid, (II) a low-molecular weight glycol component, (III) a polyoxyalkylene glycol component and/or (IV) an aliphatic polyester component is impregnated with (B) a polyallyl compound, e.g. triallyl isocyanarate, having two or more allyl groups of the formula (R1, R2 and R3 are H or organic groups) in the molecule and (C) a reaction initiator, e.g. an organic peroxide or a photochemical reaction initiator, in a solvent having no affinity for (A), and crosslinked, preferably by exposure to electron or gamma rays.
