Abstract
PURPOSE: To prepare the title article having excellent mechanical properties, light resistance, etc., by crosslinking an uncrosslinked molded article of a block copolymer composed of a crystalline linear polyester and an aliphatic linear polyester containing a specific compound.
CONSTITUTION: A composition comprising (A) 100 parts by weight of a polyester obtained by mixing and/or copolymerizing (a) 100 g of a block copolymer of a crystalline linear polyester containing an aromatic dicarboxylic acid as a main acid component and an aliphatic linear polyester, and (b) 0.001W0.5 equivalent of a compound having an aliphatic unsaturated group and stable under the melt conditions of the block copolymer, and (B) 0.01W20 parts by weight of a photo- polymerization initiator, is formed to an uncrosslinked molded article by melt molding, and crosslinked by irradiating with actinic radiation at a temperature between the room temperature and the melting point of the polyester.
