An adhesive composition comprises an epoxidized polybutadiene resin containing ethylenic unsaturation and having both terminal and internal epoxy groups and a chlorinated interpolymer of atactic polypropylene and an ethylene-propylene copolymer. The compositions may contain catalysts such as tertiary amines, Lewis acids and Lewis acid salts; or, hardeners such as primary and secondary amines, polycarboxylic acid anhydrides and polyphenols. The compositions may be dispersed or dissolved in an organic solvent or emulsified in an aqueous solution of an emulsifier such as polyvinyl alcohol or a morpholineoleic acid mixture.ALSO:Substrata are coated with films comprising the dried, consolidated residue of an adhesive composition an epoxidized polybutadiene resin containing ethylenic unsaturation and having both terminal and internal epoxy groups and a chlorinated interpolymer of an atactic polypropylene and an ethylene-propylene copolymer, with or without curing agents, solvents, dispersants and emulsifying agents. Substrata specified are aluminium, steel, wood, e.g. plywood, and plastics films and sheets of polyethylene terephthalate, polystyrene, rubber hydrochloride, polyethylene, polypropylene, polyvinyl chloride and polyvinylidene chloride. |
