BIODEGRADABLE POLYESTER-BASED BLENDS

摘要

Compositions of biodegradable polymer blends and methods for making these polymers are disclosed. A polymer blend may have a composition of at least one biodegradable polyester present in about 50 weight percent to about 90 weight percent of the polymer composition, at least one biodegradable elastomer with cross-linked epoxy functional groups, and at least one catalytic curing agent. The at least one biodegradable elastomer and the at least one catalytic curing agent can be present in a total amount of about 10 weight percent to about 50 weight percent of the polymer composition, and can be present in a weight-to-weight ratio of about 19:1 to about 1:1. Further, the polymer may have a notched Izod impact strength according to ASTM D256 of about 150 Joules/meter to about 1200 Joules/meter.
