Study on structure and performance of starch and styrene graft copolymer.

The microscopic structure of maize starch and styrene graft copolymer was analyzed by using infrared spectra and scanning electron microscopy.And through slice experiment,determination of intensity of tension,water absorbance,hot water resistance,and enzyme experiment,its biodegradation performance was analyzed.The results showed that the graft copolymerization has thermoplastic and degradation of biological,which could be used as a biodegradation material.
