Claims20
An aqueous composition useful as an adhesive comprising at least one halogenated olefin polymer, at least one high-functionality epoxy resin, and at least one diacid-modified resin that is different from said halogenated olefin polymer;
- wherein said diacid-modified resin is made by reacting one or more resins that contain carbon-carbon double bonds with one or more diacid or diacid-derivative small molecules with carbon-carbon double bonds.
An aqueous composition useful as an adhesive comprising at least one halogenated olefin polymer, at least one high-functionality epoxy resin, and at least one diacid-modified resin, wherein said halogenated olefin polymer comprises at least one polymer selected from the group consisting of chlorinated polyethylene, chlorosulfonated polyethylene, and mixtures thereof;
- wherein said diacid-modified resin comprises at least one polybutadiene adducted with maleic anhydride;
- wherein said high-functionality epoxy resin comprises at least one ECN resin;
- and wherein said composition additionally comprises
- (i) at least one dinitroso compound selected from the group consisting of dinitrosobenzenes, substituted dinitrosobenzene, dinitroso naphthalenes, substituted dinitroso naphthalenes, polymeric forms thereof, and mixtures thereof,
- (ii) at least one moiety selected from the group consisting of selenium, tellurium, compounds of selenium and sulfur, compounds of tellurium and sulfur, and mixtures thereof, and
- (iii) at least one water-soluble polymer containing pendant oxazoline groups.
An aqueous composition useful as an adhesive comprising at least one polynitroso compound;
- at least one halogenated olefin polymer;
- and at least one high-functionality epoxy resin;
- wherein said halogenated olefin polymer is selected from the group consisting of chlorinated polyethylene produced by methods other than emulsion polymerization, chlorosulfonated polyethylene produced by methods other than emulsion polymerization, and mixtures thereof;
- and wherein said composition further comprises at least one water-soluble polymer containing pendant oxazoline groups.
