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

Abstract: High polymer content compositions, containing the neutralized salt of a carboxyl-containing polymer suspended in an organic medium, are made by neutralizing the carboxyl-containing polymer in the presence of a neutralizing agent and an equal quantity of already neutralized polymer in an organic medium. These compositions are useful as thickeners and emulsifiers for aqueous solutions.

Abstract: Olefinically unsaturated carboxylic acid monomers containing at least one activated carbon to carbon olefinic double bond and at least one carboxyl group, such as acrylic acid, are polymerized in an organic media in the presence of free radical forming catalysts and at least one oil soluble ionic surface active agent selected from the group consisting of:(a) anionic surface active agents of the formula:[(R-R.sub.a ').sub.b -X].sup.- M.sup.+(b) cationic surface active agents of the formula:[(R-R.sub.a ').sub.x NR.sub.y ].sup.+ A.sup.-and(c) amphoteric surface active agents of the formula: ##STR1## wherein R is a hydrophobic moiety having eight or more carbons,R' is a hydrophilic moiety,R" is each independently hydrogen, an alkyl group, an aryl group or an alkyl/aryl group,X.sup.- is a carboxylate, sulfonate, sulfate or phosphate group,M.sup.+ is a water soluble cation,A.sup.

Abstract: A process for improving the processability of polycarbonates by contacting a polycarbonate composition with a metal salt of dodecylbenzenesulfonic acid in an amount sufficient to decrease the melt viscosity of the polycarbonate composition while increasing the impact strength.

Abstract: It has been found that the addition of small amounts of a benzoate or acetate ester of a polyfunctional hydroxy-containing compound to a maleic anhydride-containing resin greatly increases the flowability and processibility of these resins.

Abstract: It has been found that the addition of small amounts of a benzoate or acetate ester of a polyfunctional hydroxy containing compound to an olefinic nitrile copolymer composition greatly increases the flowability and processibility of these thermoplastic copolymers.

Abstract: High softening thermoplastic polymeric compositions having good impact resistance are composed of polymerized maleic anhydride, a cyclic olefin such as beta-pinene, styrene, and a preformed rubber such as a styrene-butadiene rubber.

Abstract: High softening polymeric compositions having good impact resistance are composed of polymerized maleic anhydride, an alpha-olefin such as diisobutylene, styrene and a preformed diene rubber such as a styrene-butadiene rubber.

Abstract: Polymeric compositions having good impact resistance and high softening temperatures which are composed of a conjugated diene monomer, such as butadiene, maleic anhydride, indene, and optionally styrene, are described.
