ABSTRACT:
Modified condensation polymers containing azetidinium groups, such as polyamide epichlorohydrin (PAE) resins, can be combined with amphiphilic hydrocarbons containing polyethers into 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 linting 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.
