Abstract
Disclosed is a cross-linked polyallylamine polymer composition having reduced cohesiveness, a process for producing a cross-linked polyallylamine polymer having reduced cohesiveness from an aqueous solution of a washed cross-linked polyallylamine polymer treated with a surfactant and to cross-linked polyallylamine polymer compositions produced thereby.
