ABSTRACT:
There is described a novel process of polymerizing 4-vinyl pyridine monomer in an aqueous polymerization system which comprises preparing an aqueous solution of polyvinyl alcohol, and contacting said aqueous solution of a polyvinyl alcohol with less than about 10% by weight of 4-vinyl pyridine monomer and a water-soluble initiator capable of decomposing to give free radicals.
The resultant dispersion of the novel polymerization process comprises a homogeneous, i.e., weight average molecular weight and particle size, poly-4-vinylpyridine, with no appreciable residual 4-vinyl pyridine monomer.
The resultant dispersion may be used to coat image- and ink-receiving layers of image-recording materials and ink jet recording sheets, respectively.
