Preparation and Performance of Poly(Lactic Acid)-γ-Cyclodextrin Inclusion Complex-Poly(Lactic Acid) Multibranched Polymers by the Reactive Extrusion Process
ABSTRACT The poly(lactic acid)-γ-cyclodextrin inclusion complex-poly(lactic acid) multibranched polymers were prepared by reactive extrusion process with L-lactide as raw material, stannous octoate as catalyst and the carboxyl poly(lactic acid)-γ-cyclodextrin inclusion compound as cores prepared by ultrasonic coprecipitation and carboxylation reaction. It was shown that the comprehensive performance of poly(lactic acid)-γ-cyclodextrin inclusion complex-poly(lactic acid) had been significantly improved compared with liner poly(lactic acid) by the study of structure and properties. Thus, the novel poly(lactic acid)-γ-cyclodextrin inclusion complex-poly(lactic acid) multibranched polymers have a potential use in biomedical materials. This study provided a simple and feasible preparation method for improving the performance of poly(lactic acid). GRAPHICAL ABSTRACT
