Abstract: The present invention relates to a new solvent-free preparation method of a (meth)acrylic acid polymer in solution, where said polymer has a molecular weight less than 8,000 g/mol and a polydispersity IP index between 2 and 3 by radical polymerization, the polymers obtained by this means, and their applications in industry.

Abstract: Non water-soluble polymers with a comb structure and a (meth)acrylic skeleton on which are grafted side chains containing at least one hydrophobic monomer of the styrene or (meth)acrylic ester type on C1 to C4, and at least one hydroxy or methoxy polylakylene glycol monomer. The levels of monomers are such that the polymer is amphiphilic because it is both rich in hydrophobic monomer and polylakylene glycol monomer. These products, used in paper coating dispersions, enable an increase in their Brookfield™ viscosity, a reduction in their ACAV viscosity, and an improvement in their water retention, which makes them particularly well suited for dry extract and/or high deposit speed coatings.

Abstract: 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.
