Title: (DE) DISPERSIONSMITTEL
(EN) DISPERSANTS
(FR) DISPERSANTS
Abstract:
(EN) Compound of Formula (1); wherein: Zw is an organic radical comprising w amino groups, in which w is a number and 5 ≤ w ≤ 3,000; A and B are independently oxy-C1-C20-aIkyIene carbonyl groups or oxy-C2-C20- alkenylene carbonyl groups derived from hydroxy carboxylic acids or lactones; T is hydrogen or R-CO-, where R is a C1-C50 hydrocarbyl group; Y is a C3-C4-alkylene radical linked to an amino group of Zw; Y' is an ionic salt link between an amino group of Zw and the terminal carbonyl of (A)r-(B)p-T; r and p are independently numbers between 0 and 50 and r+p>2; s, m and v are numbers; 0.99w ≤ s+m ≤ 2w; and 0.3w ≤ s+v ≤ 2w are suitable as dispersants and milling aids.
(FR) La présente invention concerne des composés représentés par la formule (1) et convenant comme dispersant et comme additif de broyage. Dans cette formule (1): Zw est un radical organique comprenant un nombre w de groupes amino tel que 5≤w≤3000; A et B sont indépendamment des groupes carbonyle d'oxy-C1-C20-aIkyIène ou des groupes carbonyle d'oxy-C1-C20-aIcényIène dérivés d'acides hydroxy-carboxyliques ou de lactones; T est hydrogène ou R-CO-, R étant un groupe hydrocarbyle en C1-C50; Y est un radical alkylène en C3-C4 lié à un groupe amino de Zw; Y' est un sel ionique de liaison entre un groupe amino de Zw et le carbonyle terminal de (A)r-(B)p-T; r et p sont indépendamment des nombres entre 0 et 50 tels que r+p>2; s, m et v sont des nombres tels que 0,99w≤s+m≤2w, et 0,3w≤s+v≤2w.
