A process for enhancing the fabrication of thermoplastic polymers entailing the addition of from 0.01 to 1 part, per hundred parts of thermoplastic polymer, of a processing aid, said processing aid comprising a processing additive, such as a silicon or a polyol, and a processing adjuvant, such as a phosphate.

Process for processing thermoplastic polymers

A method of preparing mixtures of incompatible hydrocarbon polymers using a novel compatibilizing system. The compatibilizing system comprises a mineral filler and certain reinforcement additives. Flame retardant compositions and articles fabricated from such compositions also are disclosed.

A mineral-filled thermoplastic composition is disclosed which comprises polyethylene or an ethylene-vinyl acetate compolymer; a mineral filler consisting, in the case of polyethylene, of aluminum trihydrate, magnesium hydrate, calcium carbonate or calcium/magnesium carbonates, and, in the case of the ethylene-vinyl acetate copolymer, barium titanite or neodymium titanate; and, in the case of polyethylene, an impact promoter consisting of tri(2-ethylhexyl) phosphate, isostearic acid or dodecylpyridinium salts, the selection of the impact promoter being dependent upon the mineral filler being employed, and, in the case of the ethylene-vinyl acetate copolymer, an amount of isostearic acid sufficient to increase the ductility of the composition; also disclosed is an additive composition for a thermoplastic composition which comprises a hydrophobic agent and an impact promoter.

A reinforced, filled hydrocarbon polymer composition, having increased strength and ductility, contains synergistic mixtures of at least two copolymerizable interfacial agents including an adsorbable agent and a soluble agent.

Synergistic reinforcement promoter systems for filled polymers

A reinforced, filled thermoplastic polymer composition, having increased strength and ductility, contains a reinforcement promoter having at least two reactive olefinic double bonds and a positive promoter index, based on the double bond resonance and polarity, and the promoter adsorptivity.
