Abstract
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.
