采用无机盐溶液作为溶剂的丙烯腈聚合及其纺丝的研究工作,十多年来多有报道。在聚丙烯腈纤维的工业生产上,已经应用的无机盐溶剂有硫氰酸盐溶液和氯化锌溶液等;其中以氯化锌溶液作为溶剂的丙烯腈聚合及其纺丝的研究工作,国内尚未见报道。本文采用氯化锌浓溶液作为溶剂,以过硫酸铵作为聚合的引发剂,进行丙烯腈——甲基丙烯酸甲酯共聚合反应的初步研究,探讨了本聚合体系的特点以及某些影响因素;初步考察

The research of acrylonitrile polymerization and its spinning using inorganic salt solution as solvent has been reported for more than a decade. In the industrial production of polyacrylonitrile fiber, has been the application of inorganic salt solvents such as thiocyanate solution and zinc chloride solution; of which zinc chloride solution as a solvent of acrylonitrile polymerization and spinning research, domestic Not yet reported. In this paper, we studied the copolymerization of acrylonitrile and methyl methacrylate using zinc chloride concentrated solution as solvent and ammonium persulfate as polymerization initiator, and discussed the characteristics of the polymerization system and some influencing factors. Preliminary investigation
