HIGH SOLIDS CONTENT VINYLIDENE CHLORIDE POLYMER DISPERSIONS IN STRONGLY HYDROGEN BONDED DISPERSING MEDIA AND PROCESS OF PREPARATION THEREOF

摘要

High solids content vinylidene chloride polymers, and particularly copolymers of vinylidene chloride with a comonomer containing a hydroxyl functionality, are prepared by polymerization of the monomeric ingredients of said polymers in a strongly hydrogen bonded dispersing media containing from about 0.1 to 20 percent of a dispersion stabilizer said 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 dispersion stabilizer which side chain is dispersible in said vinylidene chloride polymer, and wherein the mass ratio of (A) to (B) is from about 99:1 to 80:20.
