摘要：

Narrow molecular weight distribution fractions of poly(aryl ether ether ketone) have been prepared by hydrolysis of fractions of poly(aryl ether ether ketimine) prepolymer. The molecular weights of the prepolymer and the poly(ether ether ketone) fractions have been measured. Comparison of the molecular weight measurements indicates that the hydrolysis does not affect the backbone of the polymer. It is shown that poly(ether ether ketone) is probably protonated in methanesulfonic acid. p-Chlorophenol/ o-dichlorobenzene is a good solvent mixture for poly (ether ether ketone), probably with preferential solvation by p-chlorophenol. The Stockmayer-Fixman treatment of the intrinsic viscosity data indicate that in the unperturbed state poly(ether ether ketone) has the dimensions of a freely rotating flexible chain. The thermal properties of the poly(ether ether ketone) fractions resembles those of commercial PEEK samples. © 1990, American Chemical Society. All rights reserved.
