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

Polyvinylchloride products

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.

Method for preparing a pigment for polyvinylchloride coloring

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.

Lubricant system for polyvinylchloride, polyvinylchloride articles, and

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.

External lubricant compositions for rigid vinyl polymers

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.

External lubricant and stabilizer compositions for rigid vinyl polymers

The present invention provides an external lubricant composition for calendered vinyl polymer. The external lubricant provides rigid vinyl polymer compositions having improved plate out resistance, clarity, release, and stability. 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 greater than about 85,000 centipoises and an acid number as determined by standardized titration of KOH of between about 5 and about 9. Sheets of the calendered vinyl polymer are used for blister packs and credit cards.

Calendered rigid vinyl polymer compositions

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:

Polycarbonate processing

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

Polyvinylchloride processing

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

Polyguerbet alcohol esters

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.

Polyvinyl chloride processing

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

Polyvinyl chloride compositions and processing

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.

Lubricating and anti-tack compositions useful in the shaping of

A plastic composition with an external lubricant comprising (a) a polymer selected from the group consisting of phenoplasts and chlorine-containing thermoplastic polymers and (b) a calcium salt of a monoalkyl ester of a dicarboxylic acid where said monoalkyl contains more than 18 but less than 72 carbon atoms and said dicarboxylic acid is selected from the group consisting of succinic acid, glutaric acid, phthalic acid, terephthalic acid and isophthalic acid, where the proportion by weight of said calcium salt to said polymer is from 0.05 to 10.0:100.
