BIODEGRADABLE RESIN COMPOSITION COMPRISING CELLULOSE DERIVATIVES AND CHAIN EXTENDERS

摘要

PURPOSE: A biodegradable resin composition is provided to effectively remove acetic acid generated at manufacturing biodegradable mold. CONSTITUTION: A biodegradable resin composition comprises cellulose derivatives in chemical formula 1, and a chain extender in chemical formula 2. In chemical formula 1, R is independently H or -C(O)-X, in here X is a C1-4 alkyl group except that all R are hydrogen. R1-R4 and R6 is respectively H or a C1-4 alkyl group, R5 is a C1-4 alkyl group, x, y, and z is respectively an integer from 1-20.
