Abstract
The invention relates to a specific copolymer obtainable by co-polymerizing at least the following monomers: —more than 80 wt % of at least one bicyclic (meth)acrylate ester, —0.05 to 15% w/w styrene, and —optionally other ethylenically unsaturated monomers, 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.
Claims15
A copolymer comprising:
- 83-99.95 wt % of bicyclic (meth)acrylate esters (a),
- 0.05 to 12 wt % of styrene (b), and
- 0 to 19 wt % of ethylenically unsaturated monomers that are not monomer (a) or (b),
- up to a total of 100 wt %, wherein the weight percentages of the monomers are based on the total weight of all the monomers incorporated into the copolymer, and wherein the copolymer has a cloud point in 80:20 (v/v) petrodiesel:gas to liquid diesel fuel of 12.5° C. or lower.
