摘要: 用马来酸酐(MAH)对氯化聚丙烯(CPP)进行了接枝,以水洗法代替丙酮萃取法脱除了接枝物(CPP-g-MAH)中的副产物聚马来酸酐。对水洗接枝物进行了红外光谱表征和附着力、溶解度参数的测定,考察了温度、时间、加水量对水洗率的影响。结果表明,当温度90℃,时间2h,加水量325ml时水洗率最大;采用水洗法不影响接枝物在聚丙烯板上的附着力。

Abstract: In the paper the chlorinated polypropylene was grafted with maleic anhydrid. The polymaleic anhydride from the byproduct of CPP-g-MAH was removed by water-washing method instead of acetone extraction method. Washing graft product was characterized by infrared spectrum and the parameters of adhesion and solubility was also determined. The effect of temperature, time and water addition on the removal rate of water washing were investigated. Results showed that when the temperature was 90℃, time was 2h, water addtion was 325ml the removal rate of water washing was the highest. Using water washing method could not affect the adhesion of graft on polypropylene board.
