Associative non-ionic thickening agents containing alkyl cyclohexanol alkoxylates, their uses and formulations containing them

摘要

The present invention concerns new associative thickening agents belonging to the category of HEURs (Hydrophobically modified Ethylene oxide URethane). These products contain an original associative monomer with a base of alkyl cyclohexanol alkoxylates. Their thickening power is equal to or greater than that procured by HEUR associative thickening agents of the prior art containing grafted alkyl phenols. An efficient substitute product is therefore available, which is free of alkyl phenols, matching current market demand.

主权项

1. A hydrosoluble polyurethane consisting of the following monomers a), b) and c) in % by weight where a), b) and c) add up to 100%:
a) 75% to 99.5% of at least one polyethylene glycol of molecular mass by weight of between 8,000 g/mol and 15,000 g/mol, b) 0.5% to 10% of at least one polyisocyanate, and c) 15% to 99.5% of at least one monomer of formula (I)where:
m and n are integers of less than 150, at least one of which is non-zero, the AO group designates ethylene oxide, and the BO group designates propylene oxide; and R designates a linear alkyl group having 9 to 12 carbon atoms.
