Novel phosphorylated compositions of a vinyl chloride copolymer or terpolymer, a phenoxy resin, a hydroxyalkyl acrylate or methacrylatelactone adduct or a reaction product of a normally solid pendant-hydroxyl-containing thermoplastic polymer having at least 8 hydroxyl groups per molecular chain and an adduct which is the product of either a hydroxylalkyl acrylate or methacrylate or a lactone-acrylate adduct and an organic diisocyanate having improved dispersion characteristics suitable for use in applications such as magnetic recording media.

Phosphorylated reaction products and compositions incorporating such

A coating composition capable of substantial deformation without loss of continuity, adhesion or protective properties. The coating composition comprises a phenoxy resin mixed with a relatively soft modifier resin having certain specific properties. In a preferred embodiment, a particulate material, such as a zinc pigment, may also be included. A crosslinker may also be included.

Formable coatings

Novel vinyl chloride copolymers including a hydroxyalkyl acrylate or metacrylate or allyl alcohol, an acid functionality from carboxylic acid-containing monomers and optionally an epoxy-containing vinyl monomer in selected proportions provide suitable binder resins for applications such as magnetic recording media, imparting enhanced dispersion and magnetic property characteristics while also having desirable rheological characteristics and, when the epoxy-containing vinyl monomer is used, desirable thermal stability.

Novel vinyl chloride resins and compositions incorporating such resins

Waterborne, neutralized, carboxyl-bearing phenoxy resin with which is blended a relatively soft, neutral, non-carboxyl-bearing modifier resin. A coalescing solvent is preferably included in the aqueous blend.

Modified waterborne phenoxy resins

Described herein are tough solvent resistant materials from a crystallizable, crosslinkable resin mixture comprising a particular polyarylether and a crystallization promoting plasticizer, and reinforced composites made from such resin mixture.

Crosslinkable, crystallizable polyarylethers and composites therefrom

Flexible, self-cross-linking binders, useful for, e.g., paints and magnetic media composites, are prepared from hydroxyl-containing thermoplastic polymers reacted with condensates of diisocyanates and unsaturated esters. They can be cured with an electron beam.

Haloalkynes are polymerized to polyunsaturated compounds with a catalyst mixture consisting of a nickel compound, and a ligand in the presence of a reducing metal.

Polymerization of haloalkynes by a nickel catalyst

High-temperature coating materials are prepared by cross-linking copolymers of oligomers produced by nickel catalyzed coupling of unsubstituted aryl polyhalides with substituted organic halides.

High-temperature, aromatic coating materials from aryl polyhalides

Described herein is an integrated process for the preparation of substantially linear high molecular weight thermoplastic polymers derived from aryl polyhalide monomers. Aryl polyhalide monomers are first prepared by the reaction of an alkali metal salt of a phenol compound, e.g., dipotassium salt of bisphenol A, with a dihalobenzenoid compound, e.g., 4,4'-dichlorophenylsulfone, in a liquid phase of an aprotic solvent and an azeotrope former, e.g., toluene. Water is removed from the reaction mass as an azeotrope until substantially anhydrous conditions are attained. The aryl polyhalide monomers are then coupled by contacting the monomers with a catalyst mixture of a nickel compound and a ligand in the presence of a reducing metal, e.g., zinc, and an aprotic solvent under substantially anhydrous conditions to form substantially linear high molecular weight thermoplastic polymers.

Organic halides are reduced to a dechlorinated products with a catalyst mixture consisting essentially of a nickel compound, a triarylphosphine and a halide ion, in the presence of reducing means for maintaining nickel in the zero valent state.

Reduction of organic halides

Substituted olefins are prepared by the reaction of an organic halide with an olefin in the presence of a catalyst derived from zinc, a triarylphosphine and a nickel salt.

Preparation of substituted olefins

Aryl and heteroaryl mono chlorides are coupled in an aprotic solvent under an inert atmosphere by a catalyst mixture of a nickel compound and a ligand in the presence of a reducing metal.
