✦ Synopsis

Abstract

A method has been developed for the examination of compositions prepared from polyvinyl chloride and related polymers. Its purpose is to recover the polymer from the. composition by solution in tetrahydrofuran, followed by subsequent precipitation of the polymer with alcohol from the tetrahydrofuran solution.

Figures are given for the chlorine contents of polymers used in the preparation of compositions and of the corresponding polymers recovered from tetrahydrofuran solution; the influence of the test on the infra‐red spectra of the polymers is indicated.

The polymerization of N-vinylcarbazole in the presence of FeCl 3 -impregnated montmorillonite resulted in the formation of a poly(N-vinylcarbazole)-montmorillonite composite. XRD analysis of the composite revealed no expansion for d 001 spacing, in sharp contrast to that for the same composite prepa
