The compositions of copolymers formed under different copolymerization conditions were studied for the system acrylonitrile methyl acrylate dimethylformamide at 50"C. The relationship between the compositions of the feed and the copolymer cannot be described with sufficient accuracy either by the cl
## Abstract Co(α‐methylstyrene‐acrylonitrile)polymers with about 46 mole‐% acrylonitrile and 45≦10^−3^__M__<417 were investigated by means of light‐scattering in tetrahydrofurane as a solvent. The Zimm plots obtained are presented. The mean square radius of gyration, 〈__S__^2^〉, and the molar mass
