    摘要: A process for treating a composition containing a polyamine-epihalohydrin resin that has a low level of CPD-producing species and good gelation stability is disclosed. A polyamine-epihalohydrin resin is prepared with a ratio of epihalohydrin:amine of less than about 1.1:1.0; The resin is then subjected to a base treatment followed by an acid treatment resulting in a resin that has good gelation storage stability and produces low levels of CPD.

    摘要: This invention relates to a process for preparing polyamine-epihalohydrin resins having reduced levels of residuals. The process comprises (a) charging a membrane separation apparatus with an aqueous composition comprising at least one polyamine-epihalohydrin resin, and (b) separating the aqueous composition into a permeate and a retentate by passing the aqueous composition through the membrane of the membrane separation apparatus. The retentate comprises at least one polyamine-epihalohydrin resin having lower levels of residuals on an equal active component basis than the aqueous composition of (a). The permeate comprises residuals removed from the aqueous composition of (a) and less than 5% by weight of the active component of said at least one polyamine-epihalohydrin resin. The polyamine-epihalohydrin resins having reduced levels of residuals can be used to make wet strength agents, dry strength agents, creping adhesives for paper products, curing agents for wood product adhesives, and other products.

    摘要: The invention provides a novel poly(aminoamideureylene) resin and a process for making the resin without epichlorohydrin. The resin useful for improving wet strength of paper and paperboard intermediates. The resin is formed by making a prepolymer by reacting a diaminoamine, a dicarboxylic acid, and urea, allylating the prepolymer, and then reacting with hypohalous acid to produce an allylated quaternized poly(aminoamideureylene) having halohydrin substituents with resort to using epichlorohydrin. The resin can be activated for use in a papermaking process by treatment with a caustic (alkaline) agent. Optionally, the resin can be cross-linked prior to activation by heating in the presence of a caustic agent.The invention also provides an improvement in making polymers having halohydrin substituents formed by reacting an allylated polymer with hypohalous acid wherein the reaction is conducted without control of the pH.This invention also provides a method for producing hypohalous acid by acidifying an aqueous solution of an alkali metal hypohalite.
