A graft reaction of poly(vinyl alcohol), PVA, and polyethylene grafted width maleic anhydride has been carried out in order to add hydrophobicity to PVA. Biodegradabilities of PVA and the polyethylene derivative are well-known. The graft reaction product that was prepared by a simple procedure was characterized with FTIR, DSC, and TGA. The FTIR spectra indicated that ester bonds were formed in the product. It was also found from the thermal analysis that the graft compound was less crystalline that raw PVA and the thermal properties of the graft copolymer remarkably depended on molar ratio of succinic anhydride group in the polyethylene derivative that was used in the graft reaction. The degradation of the material will be discussed.
