Compositions for dielectric sealing applications comprising terpolymer emulsions of ethylene, vinyl esters and n-methylol comonomers blended with PVC emulsions buffered at a pH greater than 7

摘要

A binder suitable for dielectric sealing may be prepared comprising a blend of a polyvinyl halide emulsion and an aqueous emulsion comprising a vinyl ester of an alkanoic acid interpolymerized with (a) 5 to 28% by weight of ethylene; (b) 0.5 to 4% by a weight of an N-methylol containing copolymerizable monomer; (c) 0 to 3% by weight of a latex stabilizer; and (d) 0 to 1% by weight of at least one polyunsaturated copolymerizable monomer, the binder having a Tg of -15 DEG to +35 DEG C. and being buffered to a pH greater than 7.
