| 摘要 |
A polymeric composition comprises a blend of equimolar vinylidene cyanide-vinyl acetate copolymer with from 6 to 15% by weight of the total polymer of a homopolymer or copolymer of a vinyl pyridine. The vinyl pyridine may be 2-, 3- or 4-vinyl pyridine or a vinyl substituted alkyl pyridine, and may be copolymerized with vinyl acetate, acrylonitrile, styrene or methylmethacrylate, the copolymer containing at least 60 mol per cent of the vinyl pyridine. The blend of polymers is dissolved in a solvent such as dimethylformamide, acetonitrile or a mixture of acetonitrile and water, and spun into fibres which may be dyed readily. Examples are given. Specification 681,120 is referred to.
