Abstract
Polymers containing at least 60 per cent of acrylonitrile are stabilized by adding thereto 1 to 20 per cent of a stabilizer selected from N,N-dimethyl hydroxyacetamide, N,N-diethyl hydroxyacetamide, N-ethyl hydroxyacetamide, or N - methyl N - ethyl hydroxyacetamide. Polymers of acrylonitrile specified are polyacrylonitrile and copolymers with methyl acrylate, isobutylene, vinyl acetate, vinyl chloride, and vinyl pyridine, and a terpolymer with isobutylene and allyl alcohol. In an example the stabilizer is incorporated in an acetone solution of a copolymer of acrylonitrile and isobutylene, which is then cast into films.
