Abstract

A detailed examination has been undertaken of the high field 13C-NMR spectrum of various acrylonitrile/vinyl acetate copolymers prepared by radical initiation in a heterogeneous aqueous batch reaction (taken to low conversion). It has been possible to establish the triad, tetrad and pentad sequences for copolymers employing sequence patterns and peak fractions as an aid to peak assignments. These results indicate that the copolymer cotacticity is virtually independent of the comonomer feed ratio.
