MISCIBILITY AND MORPHOLOGICAL STRUCTURE OF BIODEGRADABLE BLEND OF POLY(β—HYDROXYBUTYRATE)AND POLY(D,L—LACTIDE)

摘要

The poly(β-hydroxybutyrate)/poly(d,1-lactide)(PHB/PLA)blend was foundto be immiscible,the melting point and the phase crystallinity of PHB were independent of theblend composition.Comparing with plain PHB,the blend exhibited the crystallization changeand a certain improvement of the mechanical property.
