Curable isocyanate prepolymers have been made in which all or a portion of the available isocyanate terminal groups have been reacted with a secondary amine-containing silane monomer having two trialkoxy silane groups.

Silane-containing isocyanate-terminated polyurethane polymers

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 or thermosetting resins

Bonding between thermoplastic resins and inorganic oxide substrates is 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.

Stabilized polymeric organosilane compositions

Novel compounds comprising organic copolymer or terpolymer backbones having pendent hydrolyzable organosilicon groups bonded thereto, are disclosed. Treatment of inorganic oxide surfaces with the novel compounds renders them adherent to and/or compatible with resinous media.

Process for preparing silane grafted polymers

Novel compounds comprising poly(diphenylene ether) backbones having hydrolyzable organosilicon groups bonded thereto are useful in improving adhesion between resinous media and inorganic oxide surfaces.
