CELLULOSE ACETATE BASED RESIN FOAM WITH BIODEGRADABILITY AND ALSO EXCELLENT MECHANICAL PROPERTY AND HEAT MOLDABILITY, AND CELLULOSE ACETATE BASED RESIN FOAM MOLDED ARTICLE WITH BIODEGRADABILITY AND ALSO EXCELLENT MECHANICAL PROPERTY AND DIMENSIONAL STABILITY

摘要

PROBLEM TO BE SOLVED: To provide an article obtained by using a cellulose acetate based resin foam which is biodegradable and, at the same time, excels in mechanical properties and dimensional stability. ;SOLUTION: The cellulose acetate based resin foam molded article which is biodegradable and, at the same time, excels in mechanical properties and dimensional stability is obtained by subjecting a foamable resin composition comprising 100 pts.wt cellulose acetate based resin, 10-100 pts.wt. at least one biodegradability imparting material selected from corn starch, rice flour, starch, wood flour, straw, rice hulls, lees of bean curd, wheat-gluten bread, chitin, and chitosan and, in addition, 10-100 pts.wt. at least one modifier selected from polyethylene, polypropylene, and an ethylene/vinyl acetate copolymer to heat molding, compression molding, vacuum forming or pressure forming.;COPYRIGHT: (C)2001,JPO
