摘要:
Disclosed are resin compositions that are the reaction product of epihalohydrin with a mixture of polyaminoamide and vinyl amine polymer containing a minimum of about 1 mole % vinyl amine monomer units, wherein said polyaminoamide comprises the reaction product of dicarboxylic acid, or a derivative thereof, with polyamine selected from the group consisting of methyl bis(3-aminopropyl)amine and polyalkylenepolyamine containing from two to four alkylene groups having two to four carbons, two primary amine groups, and one to three secondary amine groups. Also disclosed are a process for creping fibrous webs utilizing the resin compositions, and creped paper prepared by the process. Also disclosed is wet and dry strength paper containing the resin compositions and processes for creping fibrous webs utilizing the resin compositions as creping adhesives.
