A rheology modifier/hair styling resin which is a crosslinked, linear poly(vinyl amide/polymerizable carboxylic acid) copolymer exhibits advantageous hair care properties of high viscosity and long-lasting curl retention.

Rheology modifier/hair styling resin

This invention relates to stable, quaternized vinlypyridine carboxylate home-, co- and ter-polymers, useful as dye transfer inhibitors and polymers complexable with active agrochemical, pharmaceutical or cosmetic agents for controlled release thereof, and to a commercial process for the synthesis of said polymers in high yield and purity.

Product and process for making quaternized, water soluble vinylpyridine carboxylate polymers

This invention relates to the preparation of stable, quaternized vinylpyridine carboxylate homo-, co- and ter-polymers in high yield and purity, which polymers are useful as dye transfer inhibitors and polymers complexable with active agrochemical, pharmaceutical or cosmetic agents for controlled release thereof.

Process for making quaternized vinylpyridine carboxylate polymers using suspension polymerization

This invention relates to stable, quaternized vinylpyridine carboxylate co-polymers, useful as dye transfer inhibitors and polymers complexable with active agrochemicals or pharmaceuticals for controlled release thereof, and to a commercial process for the synthesis thereof in high yield and purity.

Product and process for making quaternized, water soluble vinylpyridine

This invention relates to an improved free radical polymerization process for directly producing stable vinylpyridine polymer particles in an aqueous suspension and in a high state of polymer purity by effecting the polymerization in the presence of a water soluble suspension agent selected from the group of polyvinyl lactam, a hydroxy-containing polymer, a polyvinyl alcohol and a mixture thereof.
