ALIPHATIC POLYESTER AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an aliphatic polyester which is hardly discolored at the time of polymerization and molding and has a sufficiently high molecular weight. SOLUTION: The aliphatic polyester is mainly composed of a diol unit and an aliphatic dicarboxylic acid unit and has reduced viscosity of at least 1.6, where the aliphatic polyester contains a monocarboxylic acid unit and/or a monoalcohol unit.
