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.“,”Synthesis of cellulosepolyacrylonitrile copolymers has been studied in homogeneous solution of dimethylacetamideLiCl. The method is based on the preliminary reaction of a part of OH cellulosic groups with the methacrylic chloride of the unsaturated acid. In a second time acrylonitrile is grafted on to unsaturated lateral double bonds. Behaviors of the copolymer are quite different from those obtained in heterogeneous condition.
