摘　　要：制备了窄分布的含酞侧基聚芳醚砜（ＰＥＳ－Ｃ）级份样品，用光散射法测定样品重均分子量，粘度法测定样品在ＤＭＦ、ＣＨＣｌ＿３和１，２－Ｃ＿２Ｈ＿４Ｃｌ＿２中的特性粘数和Ｈｕｇｇｉｎｓ参数ｋ＇值。ｋ＇值远大于０．５反映了体系中存在特殊的溶解行为。得到ＰＥＳ－Ｃ在３种溶剂中的Ｍａｒｋ－Ｈｏｕｗｉｎｋ方程：A series of narrow molecular weight distribution fractions of phenolphthalein polyarylether sulfone(PES-C)had been prepared. The of these fractions were determined by conventional light scattering method.The[η]and the Huggins slope constant k' in DMF, CHCl_3 and 1,2-dichloroethane were also determined. The Huggins constants are greater than 0. 5 in all of these solvents showing a special solubility behvior .The Mark-Houwink equations of PES-C in these solvents at 25℃ are[η]=2. 79× 10￣(-2)(DMF);[η]=3.96× 10￣(-2) (CHCl_3); [η]=7.40× 10￣(-2) (CH_2ClCH_2Cl).
