水洗法脱除CPP-g-MAH中的聚马来酸酐

Removing polymaleic anhydride from graft copolymer CPP-g-MAH with water extraction

用溶液法制备了CPP-g-MAH接枝共聚物,用水洗法脱除了CPP-g-MAH中的副产物——聚马来酸酐,考查了温度对水洗率的影响,证明了水洗法的可行性,并用FT-IR对水洗产物进行了表征。

The graft copolymer CPP-g-MAH was prepared in solution and the byproductpolymaleic anhydride was removed with water extraction. The effect of temperature on the degree of water extraction was reviewed. The feasibility of water extraction method was proved. The grafting products were characterized by means of FTIR.
