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、CHCl3和1,2-C2H4Cl2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: [η]=2.79× 10-2Mw0.615,r=0.999 8(DMF,25℃) [η]=3.96× 10-2Mw0.58,r=0.999 5(CHCl3,25℃) [η]=7.40× 10-2Mw0.52,r=0.999 5(1,2-C2H4Cl2,25℃).

Abstract: Aseries of narrow molecular weight distribution fractions of phenolphthalein polyarylether sulfone(PES-C)had been prepared.The Mw of these fractions were determined by conventional light scattering method.The[η]and the Huggins slope constant k' in DMF, CHCl3 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-Cin these solvents at 25℃ are [η]=2.79× 10-2Mw0.615(DMF);[η]=3.96× 10-2Mw0.58(CHCl3); [η]=7.40× 10-2Mw0.52(CH2ClCH2Cl).
