Good quality films can be formed on a substrate by coating a substrate with a solution comprising a liquid silicate solvent containing a dissolved photocurable arylsiloxane oligomer or polymer. Phenyl silocane/silicate compositions can be used to form photocurable films on substrates for use as dielectric films, protective coatings, and the like.

Blend of silicate and photocurable arylsiloxane materials

The hardness of coatings comprising a photocurable arylsiloxane oligomer or polymer and a liquid organosilicate can be dramatically improved by first curing the coating with ultraviolet light followed by heating.

Good quality films can be formed on a substrate by coating a substrate with a solution comprising an alkoxy alkanol solvent containing a dissolved photocurable arylsiloxane oligomer or polymer. Phenyl siloxane/silicate compositions can be used to form photocurable films on substrates for use as dielectric films, protective coatings, and the like.

Oligomers and polymers, useful as interlayer dielectric films, are formed by the co(hydrolysis/condensation) of an aryl group-containing trifunctional silanetriol or derivative with a tetrafunctional silicic acid compound. The respective tri- and tetrafunctional substituents on either silicon compound reaction are chosen so that they act as reactants in condensation oligomerization or polymerization reactions with the substituents on the other reactant.

Arylsiloxane/silicate compositions useful as interlayer dielectric films

The etching of cured arylsiloxane/silicate resin coatings with HF is improved if the curing of said coatings, prior to etching, comprises curing with energy ray irradiation.

Striation-free interlayer dielectric films of good reflectivity are formed by spin-coating a solution comprising 1,2,4-trimethylbenzene solvent containing a dissolved arylsiloxane oligomer or polymer capable of forming an interlayer dielectric film.

A laminate for the protection of motor vehicle bodies from abrasion and corrosion damage which has a film component comprising an internally plasticized vinyl chloride copolymer resin and an effective amount of a polymeric additive for improving the flexibility of the film and an adherent layer of pressure sensitive adhesive.

Laminate for the protection of motor vehicle bodies

The haze values of polyvinyl chloride compositions containing a PVC compatible plasticizer/haloalkyl phosphate flame retardant composition are improved by incorporation of an effective amount of dimethyl methylphosphonate in such a composition for improvement of such haze values.

Flame retardant plasticizer formulation for polyvinyl chloride

An interpolymer which contains a crosslinked acrylate component formed by emulsion polymerization and a polyvinyl chloride component formed by suspension polymerization also comprises an effective amount for improved impact resistance of a plasticizer which is compatible with the acrylate component and which is incompatible with the polyvinyl chloride component.
