摘要 以丙烯腈聚合物无氧热环化结构模型为依据,采用13C-NMR、DSC、IR等手段研究了共聚体系的组成和聚合溶剂各自或协同效应对聚合物结构规整性的影响。结果表明,在自由基聚合中,可以通过选择溶剂和共聚单体在一定程度上控制丙烯腈共聚物的规整度。 In this paper,effects of comonomers and solvents of copolymerization on the stereoreguIarity of AN copolymers,were studied on the basis of heat-cyclization model of PAN,The result shows that,it is possible to control the stereoregularity of AN copolymers inradical polymerization by means of comonomer and /or solvent.
