摘要:
Compositions of and processes for preparing a polyamine-polyamidoamine-epihalohydrin resin generally include reacting a first polyamine, a polyamidoamine, and an epihalohydrin to form the polyamine-polyamidoamine-epihalohydrin (PPAE) resin, wherein the polyamidoamine is prepared by reacting a polycarboxylic acid or a polycarboxylic acid derivative with a second polyamine to form the polyamidoamine, wherein a molar ratio of the polyamine to the polycarboxylic acid is 1.05 to 2.0. The PPAE resin can be used in an adhesive formulation for use in creping applications for forming paper products such as tissue products.
