Abstract: An improved process for bonding natural or synthetic fibers to elastomeric copolymers of ethylene and higher alpha-olefins or to terpolymers of ethylene, higher alpha-olefins and cyclic or acyclic dienes having non-conjugated double bonds is disclosed. The process comprises coating the fibers with an aqueous dispersion of phenol-aldehyde resin and a latex of an elastomeric ethylene copolymer or terpolymer as defined above which is grafted with an acid, water-soluble vinyl or vinylidene monomer, the aqueous dispersion having been allowed to mature for from 10 to 80 hours after preparation thereof. After the fibers are coated with the aqueous dispersion and dried, an elastomeric ethylene copolymer or terpolymer as defined above and containing a vulcanizing agent is contacted therewith and vulcanized thereon.
