Abstract
Described are preferred processes for producing linear polyvinylpyridines. The processes involve the use of hydrogen peroxide to initiate polymerization of vinylpyridine monomers in an aqueous solvent. Processes of the invention provide good reaction rates and conversions, and are particularly advantageous in achieving control of the M.sub.w 's of the final product polymers.
