MODIFIED CONDENSATION POLYMERS CONTAINING AZETIDINIUM GROUPS IN CONJUNCTION WITH AMPHIPHILIC HYDROCARBON MOIETIES

摘要

Modified condensation polymers containing azetidinium groups, such as polyamide epichlorohydrin (PAE) resins, can be combined with amphiphilic hydrocarbons in a single molecule to provide several potential benefits, depending upon the specific combination employed, including: (a) wet strength aids that impart softness; (b) softeners that do not reduce wet strength: (c) wet strength with improved wet/dry strength ratio; (d) surface feel modifiers with reduced tinting and sloughing; (e) wet strength aids with controlled absorbency; (f) wet strength aids with controlled decay rate after wetting; and (g) Yankee dryer additives that provide surface protection and adhesion with controlled release properties.
