Solid Polymer Derived From Ethylenic Reactants Only Derived From At Least One Reactant Containing An Atom Other Than C, H, O, Or Hal Patents (Class 525/175)
Abstract: The improvement of physical and mechanical properties of polar resins such as nylon and dacron resins by blending with EPM and EPDM resins which have been rendered more compatible by the modification to incorporate polar groups.
Abstract: Compatibilized blends and composites of materials containing nitrile functionality with materials normally incompatible therewith are formed by mixing the components in the presence of an acid compatibilizing agent.
Abstract: High impact compositions comprising from 80 to 60 wt % of a styrene-acrylonitrile copolymer and from 20 to 40 wt % of a cross-linked, aliphatic polyester elastomer. The polyester elastomer is produced by preparing a cross-linked latex of the polyester.
Abstract: A process for the preparation of chlorinated aliphatic polymers wherein chlorine-free polymers are chlorinated by using gaseous chlorine in chlorinated hydrocarbons as solvents and the chlorinated aliphatic polymers are recovered from the chlorinating solution by steam distillation in which process from 15 to 50% by weight of a lacquer resin is added to the chlorinating solution before steam distillation. The chlorinated polymers contain less residual solvent.

Abstract: Flame retardant resin compositions are disclosed, comprising a thermoplastic condensation polymer selected from the group consisting of polyesters, polycarbonates and polyamides, a halogenated flame-retardant, and a rubber-occluded flame retardant synergist. The compositions possess superior stability in melt processing and improved flame retardancy and impact strength.
