Abstract: A color concentrate which comprises (a) one or more of polypropylene resins and propylene copolymers having a melt flow rate in the range of 0.1-100, (b) one or more of organic and inorganic pigments; and (c) one or more pigment dispersants selected from the group consisting of polyethylene wax, polypropylene wax and derivatives thereof, zinc stearate, magnesium stearate, aluminium stearate, calcium stearate and ethylene bisamide, the contents of (a), (b) and (c) being, respectively, 11-30 wt %, 10-80 wt % and 10-50 wt % based on the total of (a), (b) and (c); and molded or extruded articles of thermoplastic resins other than (a) colored with the color concentrate.
Abstract: A composition and method for polymerization of cycloolefins using a feed stream including an iodide containing activator to form a substantially cross-linked polymeric product. The polymeric product may be formed by polymerization in an intricately shaped mold and/or be of ultra-low density. High glass transition temperature and fiber reinforced products are formed.
Abstract: Incorporation of an ethoxylated amine in a sodium benzoate nucleated propylene polymer resin synergistically improves clarity as well as yellowness over what is achieved by use of sodium benzoate or ethoxylated amine alone.
Abstract: A composition comprising an amorphous resin (excluding polyphenylene ether) and a specific diamide compound of the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are defined in the specification. The moldability of the amorphous resin is improved without reducing its heat resistance.

Abstract: An injection blow molding grade resin or improved clarity and processability is obtained by incorporating N,N.sup.1 -ethylene bisstearamide and an ethoxylated amine into a sodium benzoate nucleated propylene polymer.
Abstract: A process for producing a thermoplastic resin molding which comprises adding to a thermoplastic resin an organic compound which is compatible with said thermoplastic resin to form a homogeneous phase at a molten state of said thermoplastic resin and causes phase separation by cooling, molding the composition by melting, and solidifying it by cooling; and the molding thus obtained.
Abstract: A process for producing a styrene-base resin having improved moldability and a good hue by continuously adding a specific higher fatty acid amide in a dissolved or molten state, and/or a mixture of a specific higher fatty acid amide and a specific metallic soap in a molten state, to a styrene-base resin in the course of its production by continuous bulk or solution polymerization. The above process is particularly effective for rubber-modified styrene-acrylonitrile resins.
Abstract: A polyphenylene ether composition comprising polyphenylene ether or a composition containing polyphenylene ether and styrene resin, and a diamide compound represented by the following formula. ##STR1## This composition is improved in processability due to high flowability, with a minimum of decrease in heat resistance.
Abstract: A filled crosslinked polymeric composition of ethylene-vinyl ester copolymer which has a significant degree of flame retardancy by inclusion of a dual lubricant system which includes a fatty acid and an alkylene-bis-amide.

Abstract: Novel aqueous adhesive and coating compositions composed of (1) an aqueous emulsion (latex) or dispersion of a polymer or interpolymer of one or more vinyl monomers such as an emulsion of a copolymer of vinyl acetate and butyl acrylate and (2) an aqueous emulsion or dispersion of a polyisocyanate which has at least partially reacted with an alcohol having the formula ROH wherein R is a hydrocarbon radical having at least one carbon atom and wherein the dispersion or emulsion (2) is stabilized with a combined surfactant and alcohol having the formula R' wherein R' is a hydrocarbon radical having at least one carbon atom are described.
Abstract: Polyolefin film is produced with enhanced properties by the addition thereto of a placticizing oil, a slip promoting wax and an inert filler for imparting anti-block characteristics to the film. The three components have a synergistic effect in that the combination enhances the desirable attributes of each additive while minimizing the deleterious effects which each additive alone would have on a polyolefin film.
