发明名称 UN PROCEDIMIENTO PARA PRODUCIR UNA SOLUCION ACUOSA DE UNA POLIAMINOPOLIAMIDA QUE CONTIENE FUNCIONALIDAD HALOHIDRINA
摘要 <p>Disclosed is a novel process for producing water-soluble, cationic resins containing halohydrin functionality from basic polyaminopolyamides containing secondary amine functionality without the use of epihalohydrin. The process of this invention comprises reacting the basic polyaminopolyamide in aqueous medium with an allyl halide to form allyl substituents on tertiary nitrogen atoms, converting the allyl substituents to halohydrin moieties by reaction with hypohalous acid and then maintaining the resulting solution at a pH of at least 7.0 until the Gardner-Holdt viscosity of the solution at 24% solids and 25 DEG C. reaches at least B.</p>
