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).

Key words: Solution property of polymer, Mark-Houwink equation, Phenolphthalein poly (arylether sulfone)
