PREPARATION METHOD OF ALIPHATIC POLYESTER RESIN

摘要

The present invention relates to a preparation method of an aliphatic polyester resin which can produce the polyester resin having proper mechanical properties while maintaining biodegradability. The preparation method of the aliphatic polyester resin uses a composition which contains aliphatic dicarboxylic acid and aliphatic diol in a molar ratio of 1:1-2.
