BRANCHED POLYAMIDOAMINES

摘要

Branched polyamidoamines bearing a plurality of pendant aminoamide moieties exhibit properties which are superior to the linear polyamidoamines from which the branched polymers are derived. The branched polyamidoamine is readily prepared by reacting a linear polyamidoamine with an alkyl acrylate or methacrylate to prepare a polymer with pendant ester moieties. The ester moieties are then reacted with an alkylene diamine or a polyalkylene polyamine to produce the pendant aminoamide groups. The branched polyamidoamines possess exceptional utility as curing agents for epoxides; as demulsifiers in the demulsification of water in oil emulsions; as flocculants and dye retention additives, and to impart superior wet strength properties to paper.
