High nitrile copolymers are rendered impact resistant by inclusion therein of small amounts of epoxidized vegetable oils.

High nitrile copolymer resins containing epoxidized oil for improved

A die assembly of the present invention for extrudable materials includes a first member providing an external wall of a continuous cavity for passage of the extrudable material, a second member providing the internal wall of the cavity, a bushing for directing the flow of extrudable material within the cavity in one axial direction, a distributor interposed within the cavity, providing a restricted space therein for passage of the extrudable material, and a channel formed between the bushing and distributor through which the extrudable material flows axially and peripherally. The die assembly of the present invention can be modified for the coextrusion of two or more layers.

Die assembly providing uniform pressure and flow

Reduction of yellowing and improvement of impact strength are obtained during the processing of nitrile polymers when said polymers are heated to a plastic state in the presence of an inert gas, thereby excluding oxygen.

Method for improving color and impact strength of nitrile polymers

The invention is gasoline containing an added manganese compound to improve the octane rating of the gasoline and including a small amount of an additive selected from a group consisting of a monocarboxylic acid or its ester, a dicarboxylic acid or its monoester or diester, an alkylamine, phenol, a substituted phenol or mixture thereof.

Manganese containing fuels

The invention is gasoline, containing manganese additives, to improve the octane rating of the gasoline and including a hydrocarbon ester of citric acid.

Gasoline compositions containing manganese additives are improved by the addition of either a citrate compound having at least one alkyl group or a tetravalent tin compound having at least one alkyl group, both of which compounds must be soluble in gasoline and are added to the gasoline composition to improve the performance of the engine.
