Abstract
The invention relates to a specific copolymer obtainable by co-polymerizing at least the following monomers: —at least one bicyclic (meth)acrylate ester —at least one C8-C24-alkyl (meth)acrylate —optionally, and preferably, at least one aromatic vinyl monomer; and —optionally other ethylenically unsaturated monomers, whereby the copolymer has a weight averaged molecular weight from 400,000 to 50,000,000 Dalton, as well as to the way to synthesize them and the use of such polymers to modify the rheology of a liquid in which they are soluble.
