BIODEGRADABLE RESIN COMPOSITION CONTAINING A CELLULOSE DERIVATIVE WITH IMPROVED MECHANICAL PROPERTIES AND POLY(BUTYLENE ADIPATE-CO-TEREPHTHALATE)

摘要

PURPOSE: A biodegradable resin composition includes poly(butylene adipate-co-terephthalate) and a compatibilizer, thereby improving elongation and impact strength.;CONSTITUTION: A biodegradable resin composition includes a cellulose derivative including a repeating unit represented by chemical formula 1 and poly(butylene adipate-co-terephthalate). The cellulose derivative and polybutylene adipate nose terephthalate are mixed to the mixing ratio of 90:10-70:30. In the chemical formula 1, R is independently H or -C(O)-X where x is a C1-4 alkyl group, but R cannot be all hydrogen.;COPYRIGHT KIPO 2013
