Синтез и физико-химические свойства привитых сополимеров полилактида и мономеров акрилового ряда

Abstract

Graft polymerization of acrylic and methacrylic acids of different concentrations was carried on biodegradable polylactide matrix. UV irradiation with different exposure time to experimental samples was selected as copolymerization initiator. The effects of ultraviolet light on the polylactide was investigated in the experiment. The resulting samples were researched by acid-base titration and gravimetrically. Exposure of ultraviolet light on the molecular weight of polylactide was investigated by viscosimetry. Also, physical and chemical properties of obtain copolymers were set depending on the conditions of their preparation.
