Abstract
(EN)
The purpose of the present invention is to provide a resin composition which has excellent recyclability and is thus able to be melt molded a plurality of times. A resin composition according to the present invention contains (A) a polylactic acid, (B) an acid-modified aliphatic polyester resin and (C) a polyvinyl alcohol resin; and 0.3-15 parts by weight of the acid-modified aliphatic polyester resin (B) and 0.3-10 parts by weight of the polyvinyl alcohol resin (C) are contained per 100 parts by weight of the polylactic acid (A).
(FR)
Le but de la présente invention est de fournir une composition de résine qui a une excellente aptitude au recyclage et peut ainsi être moulée par fusion à plusieurs reprises. Une composition de résine selon la présente invention contient (A) un poly(acide lactique), (B) une résine de polyester aliphatique modifiée par un acide et (C) une résine d'alcool polyvinylique; et 0,3 à 15 parties en poids de la résine de polyester aliphatique modifiée par un acide (B) et 0,3 à 10 parties en poids de la résine d'alcool polyvinylique (C) pour 100 parties en poids de l'acide polylactique (A).
(JA)
本発明は、複数回、溶融成形が可能なリサイクル性に優れる樹脂組成物を提供することを目的とする。本発明の樹脂組成物は、ポリ乳酸(A)、酸変性脂肪族ポリエステル系樹脂(B)及びポリビニルアルコール系樹脂(C)を含有し、酸変性脂肪族ポリエステル系樹脂(B)がポリ乳酸(A)100重量部に対して、0.3~15重量部、ポリビニルアルコール系樹脂(C)が100重量部に対して0.3~10重量部である。
