POLYMER BLENDS WITH IMPROVED NOTCHED IMPACT STRENGTH

摘要

This invention relates to a blend of biodegradable polymers comprising: (A) about 70% to about 80% by weight of at least one flexible biodegradable polymer (A) having a glass transition less than about 0<°>C, (B) about 30% to about 20% by weight of at least one rigid biodegradable polymer (B) having a glass transition greater than about 10<°>C; said percentages being based on the total weight of the polymer blend; wherein said polymer blend has a notched Izod impact strength according to ASTM D256 of at least 7.5 fl-lbs/in.
