Assignee:

Union Carbide Corporation - Danbury CT

International Classification:

G11B 570

US Classification:

428413

Abstract:

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.

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C08L 6310

US Classification:

523400

Abstract:

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.

Appl. No.:

6/335521

Inventors:

Ismael Colon - Middlesex NJ

Assignee:

Union Carbide Corporation - Danbury CT

International Classification:

C08G 6540
C08G 7523

US Classification:

528174

Abstract:

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.
