Research Progress in Heat Resistant Poly(lactic acid)

Abstract

Abstract: Advances in improving the heat resistance of biodegradable poly ( lactic acid) ( PLA)were reviewed in this article. Several technologies, such as adding nucleating agents, blending with polymers with high glass transition temperature, introducing crosslinked structure, and reinforced by fiber or nano-particle were proved effective for enhancing the heat resistance of PLA, which enlarged field of application in textile, food packaging, and engineering plastics. Some commercial grades of heat resistant ploy(lactic acid) were introduced.

Key words: poly(lactic acid), biodegradability, heat resistance
