Methods of bonding between thermoplastic or thermosetting resins and inorganic oxide substrates are improved by providing to the resin/inorganic oxide interface as an adhesion promoter a combination of (a) a copolymer of an ethylenically unsaturated organic monomer and an unsaturated organosilane containing hydrolyzable groups; and (b) a monomeric hydrolytically reactive organosilane.

Bonding thermoplastic resins

Copolymer of an ethylenically unsaturated organic monomer and an unsaturated organosilane monomer is stabilized against viscosity increase and gelation by the addition thereto of a monomeric hydrolytically reactive compound chosen from the group consisting of (i) monomeric hydrolytically reactive organosilanes and (ii) trialkyl orthoformates; and an alkyl alcohol.
