    摘要: A novel composite high-nitrile fiber in which the polymers are arranged in a sheath core type configuration. One polymer of the composite filament contains a solventless, waterless, melt-processable acrylonitrile olefinically unsaturated polymer and the other polymer of the composite filament contains an organic polymer. Either polymer can be employed as the sheath or the core component of the composite filament.

    摘要: Disclosed are normally solid polymers that are the result of addition copolymerization of the monomers acrylonitrile, methyl methacrylate, .alpha.-methylstyrene and/or styrene, and indene in the presence of a preferred unsaturated rubbery polymer, said polymers containing 10-200 parts by weight rubbery polymer, 10-40 parts by weight acrylonitrile, 5-50 parts by weight methyl methacrylate, 5-45 parts by weight of one or both of styrene and .alpha.-methylstyrene and 4-45 parts by weight indene in the polymer structure, per 100 parts by weight of the total parts of acrylonitrile, methyl methacrylate, styrene, .alpha.-methylstyrene and indene combined in said polymer structure. Also disclosed are vinyl chloride polymers compounded therewith to increase the heat distortion temperature as well as the impact resistance.
