Abstract: Polymers, oligomers or copolymers, having a dendrimer structure and containing electronegative heteroatoms, such as etheric oxygens, capable of complexing with cationic species, for use in ionically-conductive polymeric electrolytes, Relatively high ambient conductivity is a feature of such electrolytes.

Abstract: An epoxy resin composition capable of application at elevated solids levels is disclosed. The composition is produced by low temperature catalytic fusion of (a) a glycidyl ether of bisphenol A and (b) a glycidyl ether of bisphenol A containing a fusion catalyst with (c) tetrabromobisphenol A.This composition may be utilized to facilitate forming improved epoxy coatings and laminates.

Abstract: Curing agents for mixed di- and tetra-functional epoxy resin laminating compositions comprise a mixture of dicyandiamide and from 0.01 to 1 parts per part of dicyandiamide of a tetraalkylguanidine. B-staged prepregs for cores and for multi-layer bonding sheets having superior storage stability and adapted to provide reproducible multilayer laminates are made from laminating compositions employing the new curing agent combination.

Abstract: The invention relates to polymeric coating compositions which are at least partially soluble in water.Polyesters, polyesterimides, polyesteramides, polyesteramideimides, polyester hydantoins and polyester urethanes are prepared with free carboxyl or carboxylic acid groups. At least part of the carboxylic acid groups are neutralized with amine containing material producing a coating composition which is at least partially soluble in water. The coating compositions are particularly useful as electric insulating coatings or wire enamels which are readily coated on a metallic or other substrate and when cured from coatings having good electrical and physical properties.

Abstract: In a bowling lane having a decorative laminate surface, an internal lubricant in the resin for the laminate surface obviates the need for oil treatment or conditioning of the surface.

Abstract: The surface smoothness of decorative laminate pressed without pans is improved by using as a pressure equalizing medium during consolidation of the laminate lay-up under heat and pressure, a thermoplastic resin layer between successive laminate lay-ups which melts or softens and flows at the consolidation temperature, the thermoplastic resin layer being protected on either side by a release medium. The use of the thermoplastic resin layer eliminates the use of the usual highly polished metal caul plates for all but the smoothest laminates and permits the use of press build-ups of many more laminate lay-ups than when using metal caul plates.
