Associative ionic thickening agents containing alkylcyclohexanol alkoylates, their uses and formulations containing them

摘要

New associative thickening agents belonging to the category of HASEs (Hydrophobically modified Alkali-Soluble Emulsions). These products contain an original associative monomer with a base of alkylcyclohexanol akoxylates. Their thickening power is greater than the HASE associative thickening agents of the prior art containing grafted alkyl phenols. An efficient substitute product is therefore available, which is free of alkyls phenols, matching current market demand.

主权项

1. A HASE-type emulsion, comprising water and a polymer comprising polymerized units of:
a) (meth)acrylic acid, b) an ester of (meth)acrylic acid, and c) a monomer of formula (I):wherein:
m and n are independent integers of less than 150, at least one of which is non-zero, A and B designate alkyl groups which are different one from another, and have 2 to 4 carbon atoms, R′ designates a polymerizable unsaturated group, R designates a linear or branched alkyl group containing 8 to 20 carbon atoms, or a monomer of formula (I) in which at least one of the -(AO)— and -(BO)— groups are reversed in direction such that -(AO)— is —(OA)- and -(BO)— is —(OB)—.
