A crude phosphate ester product can be purified by first washing it with chelating agent composition (such as a dilute acidic solution) and then, preferably, water, drying the resulting product, and then treating the resulting product with an acid scavenger, as exemplified by an epoxy-containing compound, such as 3,4-epoxy cyclohexyl methyl-3,4-epoxy cyclohexyl carboxylate.

Epoxy-stabilized polyphosphate compositions

Epoxy functional copolymers of a higher .alpha.-olefin, and an unsaturated dicarboxylic acid ester formed by copolymerization of olefin, acid ester and ethylenically unsaturated glycidyl compound can be used to form nitrogen, oxygen, phosphorus and/or sulfur-containing lubricant additives by reaction of the epoxy functionality in such a copolymer with glycidyl-reactive compounds containing nitrogen, oxygen, phosphorus and/or sulfur atoms. Alternatively, the copolymerization reaction can utilize the olefin, unsaturated acid ester, and an ethylenically unsaturated compound containing the nitrogen, phosphorus and/or sulfur atom, which compound is formed by reaction of ethylenically unsaturated glycidyl compound and an epoxy-reactive nitrogen, phosphorus, and/or sulfur-containing compound.

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.

Blend of solvent and photocurable arylsiloxane materials

Organic solvent soluble alkoxides of magnesium, calcium, strontium, barium, scandium, yttrium and lanthanum are prepared by the reaction of these elements with alkoxy alcohols.

Organic solvent soluble polyvalent metal alkoxy alkoxides

Organic solvent soluble zinc alkoxides are prepared by the reaction of dialkyl zinc with an alkoxy alcohol.
