Method of preparing aqueous solutions of polyvinyl-pyrrolidone homopolymer of various molecular weights using a single initiator system consisting essentially of t-Butylperoxypivalate

摘要

Vinylpyrrolidone is polymerized using free radical initiator consisting essentially of t-Butylperoxypivalate and preferably in solvent consisting essentially of water, isopropyl alcohol, sec. butyl alcohol or mixtures thereof.
