Abstract
PURPOSE: To obtain a crosslinked polyester having improved mechanical properties, heat and chemical resistance, by emitting radiant rays to a specific linear block copolyester.
CONSTITUTION: A specific linear block copolyester, comprising 20W80 wt.% of a polyoxyalkylene glycol and/or an aliphatic polyester having an average molecular weight of 300W5,000 and a ratio between the numbers of carbon and oxygen of 2.0W4.5 as soft segments and 80W20 wt.% of an aromatic polyester as hard segments, and 0.1W10 mol% based on the total acid component forming the polyester of a compound shown by the formula I or II [R1W4 are the same or different H or organic group having no ester-forming functional group; A and B are carboxyl groups or hydroxyl groups; both m and n are 1W2 respectively (when A and B are hydroxyl, both A and B are 1 respectively); both K and l are 0W2 respectively and k + l are 2] having two ester-forming functional groups, is irradiated by 0.1W100 Mrad of radiant rays of wave length not more than 300 Å.
