ABSTRACT:
Crosslinkable copolymers of (a) 80-99% by wt. vinylpyrrolidone (VP) and 1-20% by wt. of a tertiary-amine-containing polymerizable monomer, e.g. vinylimidazole (VI) or 4-vinylpyridine (VPy), and (b) 80-99% by wt. VP and 1-20% by wt. of an epoxide-containing polymerizable monomer, e.g. allyl glycidyl ether (AGE) or glycidyl acrylate (GA), are reacted in solution, e.g. water, alcohol, or mixtures thereof, at a predetermined temperature, e.g. 50.degree.-70.degree. C., in a wt. ratio (solids basis) of (a):(b) of about 2:1 to 1:2, preferably about 1:1, in a solution concentration of about 10-30% of each, to provide a crosslinked PVP product, in gel form, suitable for use as an electrolead on a conductive foilbacking, or for bandages and wound dressings, and as a controlled release media for pharmaceuticals.
