摘　　要：联用宽分布ＶＤＣ－ＭＡ悬浮共聚物试样的［η］和ＧＰＣ谱图数据，确定了此共聚物在四氢呋喃溶剂中、３０℃下的Ｍａｒｋ－Ｈｏｕｗｉｎｋ常数：Ｋ＝２．５４×１０－２，α＝０．６７５７。进一步研究了单体配比、转化率、引发剂浓度以及聚合温度等因素对于分子量及其分布的影响，并建立了分子量模型。In this paper,GPC and intrinsic viscosity measurements of wide-distribution VDC-MA(mass ration 93:7)suspension copolymer in tetrahydrofuran at 30℃ were done to determine Mark-Houwink constants.The values of K=2.541×10-2,and α=0.6757 were obtained.Further more,the influence of monomer composition,conversion,concentration of initiator,and polymerization temperature on MW and MWD were analysized.The correlation for MW vs.concertration of initiator and polymerization were obtained.
