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.

Amphoteric amine based polymers having a net cationic charge and process

Cyclic amine based polymers and process for their production

An amino acid based polymer, oligomer or copolymer containing at least 5 mol % of units of a basic amino acid selected from the group consisting of lysine, argenine, ortnithine, trgptophane and mixtures thereof and at least about 5 mol % of a polymerizable compound selected from the group consisting of aliphatic or cycloaliphatic amines, alicyclic amines, diamines, triamines, tetraamines, aliphatic amino alcohols or mixtures thereof, an a process for the production of the said polymer, oligomer or copolymer by condensing at a temperature of at least 120.degree. C. said basic amino acid with at least one of said polymerizable compounds.
