ABSTRACT:
Disclosed are novel water-insoluble, water-dispersible thermosettable cationic resins derived by reaction of a water-soluble aminopolyamide, a hydrophobizing compound such as a ketene dimer and an epihalohydrin such as epichlorohydrin. The thermosettable cationic resins are water-dispersible, and aqueous dispersions thereof are stable for prolonged periods of time at relatively high solids concentration. The thermosettable cationic resins have particular utility in the sizing of paper.
