A copolymer of acrylonitrile/oxoethylene containing 121/2 moles of oxoethylene per 100 moles of acrylonitrile was prepared by (a) copolymerising a mixture of acrylonitrile and tertiarybutyl vinyl ether dissolved in dimethyl sulphoxide solvent using azobisisobutyronitrile as an initiator to form an acrylonitrile/butoxyethylene copolymer, (b) dissolving the copolymer in an aqueous solution of sodium thiocyanate and hydrolysing the tertiarybutoxy grouping with hydrobromic acid to form an acrylonitrilehydroxyethylene copolymer and (c) oxidising this copolymer with dimethyl sulphoxide/acetic anhydride to form the acrylonitrileoxoethylene copolymer. The experimental details are as follows:
