The biodegradation Characteristic polyester resin constituent and from that the foaming body and the compact null

摘要

PROBLEM TO BE SOLVED: To provide a biodegradable polyester resin composition capable of improving molding workability, while keeping heat resistance, a foaming property, operability, dimensional stability and the like which are exhibited in a conventional cross-linked biodegradable polyester resin composition.;SOLUTION: This biodegradable polyester resin composition is a resin composition obtained by melt-kneading 100 pts.mass of biodegradable polyester resin A containing 50 mol.% or more of α- and/or β-hydroxy carboxylic acid unit, 0.01-20 pts.mass of (meth)acrylate compound B having two or more of (meth)acryl group in a molecule, or one or more of (meth)acryl group and one or more of glycidyl group or a vinyl group, and 0.01-20 pts.mass of peroxide C, and contains further 0.1-20 pts.mass of a crystallization retarder D in the resin composition.;COPYRIGHT: (C)2009,JPO&INPIT
