Described are preferred processes for preparing quaternary amine polymers of good color, comprising preparing a free base amine polymer by polymerizing a free base amine monomer in the presence of a water-soluble azo initiator, and subjecting the resultant polymer to quaternization conditions. Also described are unique, water-soluble quaternary amine polymers obtainable by such processes, and dye complexing polymer blends useful in the manufacture of detergents.

H.sub.2 O.sub.2 -catalyzed polymerizations for linear polyvinylpyridines

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.
