Abstract
Abstract VINYLIDENE HALIDE POLYMERS CAPABLE OF BEING CURED AT LOW TEMPERATURES ARE PREPARED BY THE EMULSION POLYMERIZATION OF ONE OR MORE VINYLIDENE HALIDE MONOMERS WITH A CARBOXYLIC ACID MONOMER AND AN N-ALKYLOL AMIDE MONOMER IN AN AQUEOUS SYSTEM. THE RESULTING POLYMERS DEVELOP OPTIMUM OR NEAR OPTIMUM PHYSICAL PROPERTIES UPON CURING AT ROOM TEMPERATURE OR AT TEMPERATURES UP TO ABOUT 225*F.
