Adhesion promoter and self-priming resin compositions and articles made therefrom

A composition comprising:

• a) a silane which is a hydrolyzed or partially hydrolyzed alkoxysilane or acyloxysilane,
• b) a solvent consisting of an organic liquid or mixture of two or more organic liquids in which component (a) and component (c) are soluble and
• c) a crosslinking prepolymer, oligomer, resin or mixtures thereof that forms a low dielectric constant crosslinked polymer that is a polyphenylene, wherein the silane has been hydrolyzed with from about 10 percent of a stoichiometric amount to an amount of water required for complete hydrolysis.

The composition comprising:

• a) hydrolyzed or partially hydrolyzed vinyl triacetoxysilane,
• b) a solvent consisting of an organic liquid or mixture of two or more organic liquids in which component (a) and component (c) are soluble and
• (c) a crosslinking prepolymer, oligomer, resin or mixtures thereof that forms a low dielectric constant crosslinked polymer that is a polyphenylene.

A composition comprising:

• a) a silane which is a hydrolyzed or partially hydrolyzed alkoxysilane or acyloxsilane,
• b) mesitylene and
• c) a crosslinking prepolymer, oligomer, resin or mixtures thereof that forms a low dielectric constant crosslinked polymer that is a polyphenylene.

An article comprising

• (a) a substrate that has a surface comprised of a first material that is a metal, ceramic or polymer and a second material that is (i) a metal, ceramic, or polymer and (ii) different than the first material and
• (b) a coating adhered to the surface of the substrate, the coating being comprised of a crosslinked low dielectric polymer that is a polyphenylene of a crosslinking prepolymer, oligomer, resin or mixtures thereof and a silane which is a hydrolyzed alkoxysilane or acyloxysilane.
