摘要： Disclosed are copolymers of alkyl methacrylate monomers wherein said alkyl methacrylate monomers comprise at least: a. Monomers (A) selected from C6-C10 alkyl methacrylate monomers, and b. Monomers (B) selected from C10-C18 alkyl methacrylate monomers, wherein the mass ratio of Monomers (B) in the copolymer to Monomers (A) in the copolymer is about 99:1 to about 60:40 by weight. In some cases, the copolymers are of lauryl methacrylate and C8alkyI methacrylate. Also disclosed are methods for the preparation of the copolymers.

摘要： The invention relates to specific copolymers obtainable by co-polymerizing at least the following monomers: •at least one bicyclic (meth)acrylate ester •at least one lower-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 of from 100,000 to 10,000,000 D, determined using GPC-MALS techniques for a solution in THF at 40° C., as well as to the way to synthesize such copolymers and the use of such polymers to modify the rheology of a liquid in which they are soluble.
