ABSTRACT:
A dielectric coating for use on electroconductive papers consisting essentially of an interpolymer containing about 80 parts by weight of vinylidene chloride and at least about 1 part by weight of a vinyl acid, said interpolymer being obtained by polymerization in non-aqueous dispersion (NAD) comprising a strongly hydrogen bonded dispersing media containing from about 0.1 to 20 percent of a preformed dispersion stabilizer comprising the reaction product of (A) tripropylene glycol methylether acrylate and (B) at least one reactive comonomer capable of forming a side chain on said stabilizer which side chain is dispersible in said vinylidene chloride interpolymer and wherein the mass ratio of (A) to (B) is from about 99:1 to 80:20.
