Abstract:
A creping adhesive for preparing creped paper comprising an admixture of from about 0.1 to about 50 weight percent of a first polyamide-epihalohydrin resin and from about 99.9 to about 50 weight percent of a second polyamide-epihalohydrin resin, said first polyamide-epihalohydrin resin and said second polyamide-epihalohydrin resin each being made by the reaction of a polyalkylene polyamine having at least one secondary amine group with a dicarboxylic acid to form a long chain polyamide containing the recurring groups:--[--NH(C.sub.n H.sub.2n --NH).sub.p --CO--(CH.sub.2).sub.m --CO--]--wherein n=1 to 8; p=2 to 5; m=0 to 10; and whereby the resultant reaction of each said first and said second polyamide-epihalohydrin resin is further reacted with epihalohydrin to produce said each first and second polyamide-epihalohydrin resin; and said first polyamide epihalohydrin resin having a mole ratio of said epihalohydrin to said secondary amine groups of said polyamide from about 0.5:1.0 to about 1.8:1.0, and said second polyamide-epihalohydrin resin having a mole ratio of said epihalohydrin to said secondary amine groups of said polyamide less than 0.5:1.0.
