在 N,N二甲基乙酰胺氯化锂的均相溶液中研究了纤维素 -丙烯腈共聚物的合成 .先将纤维素的部分羟基同甲基丙烯酰氯反应 ,然后将丙烯腈同上述改性纤维素进行接枝反应 .所得共聚物的性能与异相条件下接枝的产物完全不同
The synthesis of cellulose-acrylonitrile copolymer was studied in a homogeneous solution of N, N-dimethylacetamide lithium chloride. Part of hydroxyl groups of cellulose were reacted with methacrylic acid chloride, and then acrylonitrile Cellulose grafting reaction of the resulting copolymer performance and heterogeneous grafting products completely different
