文摘Degradable graft copolymers of vinyl acetate and sericin were prepared firstly. Their structures, mechanical and biodegradable properties, and thermal stability were examined by IR, TG and the tensile machine.The results indicate that the graft copolymers prepared have higher tensile strength, Youngs modulus, elongation, thermostability and degradation rate than poly(vinyl acetate).
