摘要：

Starch-based biodegradable low-density polyethylene (LDPE) films were used for graft copolymerization of vinyl acetate with ceric ammonium nitrate (CAN) in aqueous acidic medium as redox initiator with nitric acid. The extent of grafting was examined by Fourier-transform infrared (FTIR) spectroscopy, attenuated total reflectance (ATR) spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The objective behind the grafting of vinyl acetate onto the LDPE-starch biodegradable films is to make these suitable for printing and packaging applications without affecting the biodegradability of the original films.
