Abstract
A composition comprising one or more high molecular weight resins and one or more low molecular weight resins in a ratio of about 1:99 to about 99:1 based on polymer actives, wherein said high molecular weight resins are selected from the group consisting of glyoxylated polyacrylamide, crosslinked polyaminoamide and polyaminoamide-epihalohydrin resins having a molecular weight of about 100,000 to about 5,000,000 Dalton and the low molecular weight resins are selected from the group consisting of glyoxylated polyacrylamide, crosslinked polyaminoamide and polyaminoamide-epihalohydrin resins having a molecular weight of less than about 100,000 Dalton and wherein the mole ratio of epihalohydrin to secondary nitrogen atoms in the high and low molecular weight polyaminoamide-epihalohydrin resins is less than about 0.5. and use of the composition for creping paper webs.
