  • Patent number: 6147183
    Abstract: Amphoteric amine based polymers having a net cationic charge, wherein the polymers are obtained by reacting (a) at least one amine with (b) at least one crosslinking agent, in a molar ratio of (a):(b) of from 2:1 to 1:1.5 and (c) reacting the condensation products of (a) and (b), which are free of anionic groups, with an anionic group containing an alkylating agent or oxidizing their tertiary nitrogen atoms to N-oxides in such an amount that the resulting polymers still have a net cationic charge, and a process for the production of amphoteric amine based polymers having anet cationic charge by reacting the compounds of (a), (b) and (c) the amphoteric amine based polymers may be used as additives in detergents.
