✦ Synopsis
A high molecular weight poly(N-acryloyl-o-aminobenzoic acid) has been synthesized by radical polymerization in a mixed solvent medium. The polymer has been fractionated by fractional precipitation and the fractions characterized by viscometry, vapour pressure osmometry and gel permeation chromatography. Mark-Houwink Kuhn-Sakurada relationships are developed for three solvents. The values of unperturbed dimensions. ((R~)/M) °5, are evaluated by application of two-parameter theories of the excluded volume effect, developed by Fixman, Kurata, Stockmayer and Roig and by Bueche and James and first order perturbation theory, Based on the value of the conformational parameter a, the polymer is found to behave as a semiflexible polymer in solution as a result of the increased bulk of the lateral group.
