Agent for obtaining a stable aqueous composition comprising particles in suspension

摘要

Agent for obtaining a stable aqueous composition comprising an association:
of a polymer constituted by:
at least one A monomer of acrylic acid and/or methacrylic acid and/or any of their salts,at least one B monomer of alkyl acrylate and/or methacrylate, andAt least one crosslinking D monomer, andwith at least one C compound corresponding to the following formulae (I):
R1-O-[(EO)n(PO)n′(BO)n″]—Z  (I)in which:R1 represents an ethyl, isopropyl or sec-butyl radical,[(EO)n(PO)n′(BO)n″] represents a polyalkoxylated chain constituted of alkoxylated units, distributed into blocks, alternatively or statistically, chosen from among EO ethoxylated units, PO propoxylated units and BO butoxylated units, representing, independently from each other, 0 or a whole number between 1 and 150, the sum of n, n′ and n″ not being null, andZ represents a fatty chain, linear or branched, of at least 16 carbon atoms.

1. An agent comprising a polymer and a fatty chain compound of formulae (I), wherein:
said polymer comprises:
at least one A monomer selected from acrylic acid, methacrylic acid and their salts,at least one B monomer selected from alkyl acrylate and alkyl methacrylate, andat least one crosslinking monomer D, and formulae (I) is:
R1O-[(EO)n(PO)n′(BO)n″]—Z  (I) in which: R1 is an ethyl, isopropyl or sec-butyl radical, [(EO)n(PO)n′(BO)n″] is a polyalkoxylated chain of ethoxylated units EO, propoxylated units PO and butoxylated units BO, distributed into blocks, alternatively or statistically, n, n′, n″ represent, independently of each other, 0 or a whole number varying from 1 to 150, the sum of n, n′ and n″ not being zero, and Z is a linear or branched fatty chain of at least 16 carbon atoms.
