The present invention relates to new associative monomers, terminated by a hydrophobic chain with a base of polycosanols, which can be bio-resourced raw materials, and notably of octacosanol. It also concerns the HASE-type associative copolymers manufactured from these monomers, from (meth)acrylic acid and from an ester of one of these acids. The invention also concerns the use of these copolymers as thickening agents for water-based formulations.
