Process for radiation grafting hydrogels onto organic polymeric substrates
Creators
Description
The process comprises the steps of incorporating an effective amount of cupric or ferric ions in an aqueous graft solution consisting of N-vinyl-2-pyrrolidone or mixture of N-vinyl-2-pyrrolidone and other monomers, e.g., 2-hydroxyethyl methacrylate, 2-hydroxyethyl acrylate, propylene glycol acrylate, acrylamide, methacrylic acid and methacrylamide, immersing an organic polymeric substrate in the aqueous graft solution, and subjecting the contacted substrate with ionizing radiation
