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 alcohol/water 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.
