【Abstract】 A study was made on the graft copolymerization of acrylamide onto polyethylene. The effects of the reaction conditions on the graft degree and the relation between the gratt degree and the moisture absorption were investigated. The graft copolymer structure was characterized by infrared spectrum and SEM. The effects of grafting degree and polyvinyl chloride content on the tensile strength of the blend were studied. The results showed that when the grafting degree was about 10% and polyvinyl chloride content was 30% , the blend system had a better tensile strength.更多还原
