MULTI-LAYER RESIN STRUCTURE

摘要

PROBLEM TO BE SOLVED: To obtain a multi-layer resin structure including an aliphatic polyester resin layer which is improved in adhesive strength as a whole including heat resistance by inserting an adhesive resin layer which shows high adhesive strength, i.e. is high in general purpose properties even between it and a polyolefin layer which is most difficult to develop adhesive strength as another thermoplastic resin between the aliphatic polyester resin layer and another thermoplastic resin layer. SOLUTION: A composition comprising a carboxyl-modified polyolefin as a main component and an epoxidized polyolefin is used as the adhesive resin. COPYRIGHT: (C)2004,JPO&NCIPI
