Abstract

Condensation products of basic amino acids with copolymerizable compounds which are obtainable by condensing PA1 (a) a basic amino acid selected from the group consisting of lysine, arginine, ornithine, tryptophane and mixtures thereof, PA1 (b) a copolymerizable compound selected from the group consisting of saturated monobasic carboxylic acids, unsaturated mono-basic carboxylic acids, polybasic carboxylic acids, carboxylic acid anhydrides, diketenes, monohydroxycarboxylic acids, polyhydroxycarboxylic acids and mixtures thereof, and optionally PA1 (c) at least one compound selected from the group consisting of amines, lactams, non-proteinogenic acids, alcohols, alkoxylated alcohols, alkoxylated amines, amino sugars, carbohydrates and sugar carboxylic acids in a molar ratio of (a):(b) of from 100:1 to 1:1 at a temperature of at least 120.degree. C., and a process for the production of said condensation products by condensing compounds (a) and (b) and optionally (c) at a temperature of from 120.degree. to 300.degree. C.
