A high nitrile fiber formed from an acrylonitrile olefinically unsaturated multipolymer which fiber is produced by a waterless, solventless melt spinning process.

Melt spun acrylonitrile olefinically unsaturated fibers and a process to

A melt processable high nitrile multipolymer such as an acrylonitrile olefinically unsaturated, multipolymer, which is stabilized by admixing with maleic acid, derivatives of maleic acid, salts of maleic acid, maleic anhydride, maleamides, salts of maleamides, maleates, salts of maleates, and combinations thereof.

Stabilizers for high nitrile multipolymers

Disclosed are compositions which are blends of vinylidene chloride-vinyl chloride copolymers with certain indene or 3-methylindene containing polymers.

Vinylidene chloride copolymer compositions

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.

Poly(vinyl chloride) compositions and polymeric blending agents useful

A composition comprising an intimate admixture of (a) 50 to 98 parts by weight of a vinyl chloride polymer having an inherent viscosity of at least 0.4, and (b) 50 to 2 parts by weight of an addition terpolymer containing acrylonitrile, indene and a third monomer selected from methyl methacrylate or at least one monomer of the group .alpha.-methylstryene and vinyl aromatics of the formula: ##STR1## where each R is independently selected from Cl, H and a C.sub.1 to C.sub.9 alkyl group and x=1 or 2, combined in the polymer structure such that
