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

Key words: Sericin, Vinyl acetate, Degradable graft copolymers
