OUTSTANDINGLY HEAT RESISTANT POLYLACTIDE RESIN AND A PRODUCTION METHOD FOR THE SAME

摘要

The present invention relates to an outstandingly heat resistant polylactide resin, to a production method for the same and to a polylactide resin composition comprising the same. The polylactide resin features high polymerisation activity even when there is a low catalyst content during the use of an organic coordinated metal catalyst, and is provided in an outstandingly heat resistant state and substantially suppresses the rate of thermal decomposition including depolymerisation and molecular weight reduction due to thermal decomposition at high temperature, even with a low catalyst content and resin acidity.
