Abstract: The present invention describes an advantageous way of lubricating polyvinylchloride during an extrusion process.

Abstract: The present invention describes polyvinylchloride processing, commonly by extrusion, which may be utilized to obtain high impact resistance and low gloss polyvinylchloride articles.

Abstract: The present invention describes an advantageous way of lubricating polyvinylchloride during an extrusion process.

Abstract: A system providing desirable properties for introducing a pigment to a polar polymer such as polyvinylchloride resin is disclosed. The system also is valuable in that pigments are conveniently dissolved or dispersed and blended in an a polyester component which is otherwise useful for polar polymer processing. Also disclosed is the mixing of the polyester component, phthalocyanine compounds, and the polyvinylchloride resins. Stronger color development is obtained by using the system of the present invention.

Abstract: A lubricant system providing desirable properties for both internal and external lubricity for polyvinylchloride resins is disclosed. Also disclosed is the use of the lubricants disclosed herein in an extruder. Polyvinylchloride articles obtained using the lubricant mixture of the present invention and/or the extrusion method are also described herein.

Abstract: This invention describes an improved lubricating system for polyvinylchloride and other plastic. In particular the present invention describes compositions having excellent metal release properties for the plastics industry.

Abstract: The present invention provides an external lubricant composition for lead stabilized vinyl polymer. The external lubricant functions as both an external lubricant and a processing aid by speeding fusion and thus, obviates the need for a separate processing aid. The external lubricant comprises an effective amount for lubricating vinyl polymer of polyethylene having a Brookfield viscosity at a temperature of 150.degree. C. of between about 1000 and about 100000 centipoises and an acid number as determined by standardized titration of KOH of between about 1 and about 40.

Abstract: A lubricant system providing desirable properties for both internal and external lubricity for polyvinylchloride resins is disclosed. Also disclosed is the use of the lubricants disclosed herein in an extruder. Polyvinylchloride articles obtained using the lubricant mixture of the present invention and/or the extrusion method are also described herein.

Abstract: The lubricant which is incorporated into the polycarbonate resin is a complex ester formed by partial esterification of pentaerythritol with a C.sub.5 to C.sub.9 aliphatic carboxylic acid followed by reaction with a C.sub.4 to C.sub.8 aliphatic dicarboxylic acid to form a material represented by the structural formula:[RCO.sub.2 CH.sub.2 ].sub.3 CCH.sub.2 O[CO(CH.sub.2).sub.x CO.sub.2 CH.sub.2 C(CH.sub.2 O.sub.2 CR).sub.2 CH.sub.2 O].sub.y --CO(CH.sub.2).sub.x CO.sub.2 CH.sub.2 C[CH.sub.2 O.sub.2 CR].sub.3wherein the above formula y has an average value of from 3 through 12; x has a value of 2 to 6 and R is an aliphatic hydrocarbon group of from 5 to 9 carbon atoms.

Abstract: The present invention describes an advantageous way of lubricating polyvinylchloride during an extrusion process.

Abstract: This invention deals with the production and use of a diacid ester formed from the reaction of the diacid and a guerbet alcohol.

Abstract: The present invention describes the manufacture of polyvinyl chloride compounds containing an organo-tin compound and a partial ester which functions both as an internal lubricant and as a co-stabilizer to scavenge hydrochloric acid thereby lessening thermal degradation of the product.

Abstract: The present invention describes the use of particular partial esters of pentaerythritol as agents for lowering the viscosity of polyvinyl chloride resin materials.

Abstract: Mixtures of (A) mixed esters of (a) C.sub.2-10 alkanepolyols, (b) certain dicarboxylic acids, and (c) C.sub.12-30 aliphatic hydrocarbon monocarboxylic acids, said esters having hydroxyl and acid numbers of 0 to 6 and having a molecular weight above 524, and (B) esters of C.sub.32-72 aliphatic monools with C.sub.18-72 aliphatic hydrocarbon monocarboxylic acids (the weight ratio of A to B being between 9:1 and 1:3) are useful as lubricants and detackifiers in thermoplastic molding compositions.
