Abstract:
Copolymers comprising ethylene, vinyl esters, in particular vinyl acetate and esters of (meth)acrylic acid, selected from esters comprising branched alkyl, cyclic alkyl or optionally alkyl substituted aryl moieties and having a weight average molecular weight of 35,000 g/mol to 150,000 g/mol, formulations of such copolymers in organic solvents and their use as pour point depressant, wax inhibitor and flow enhancer for crude oils.

Claim (Index 26):
A copolymer (A) comprising ethylene, a vinyl ester, and a (meth)acrylate, wherein the copolymer (A) comprises\n (M1) 83.5 mol % to 96.5 mol % of ethylene, (M2) 3 mol % to 11.5 mol % of at least one vinyl ester of the formula H 2 C\u2550CH\u2014O\u2014(O)C\u2014R 1  (I) where R 1  is H or a C 1 \u2014 to C 4  alkyl moiety, and (M3) 0.5 mol % to 5 mol % of a (meth)acrylate of the formula H 2 C\u2550C(R 2 )\u2014COOR 3  wherein R 2  is H or methyl, and R 3  is selected from the group consisting of\n R 3a : branched alkyl moieties having 4 to 18 carbon atoms, \n R 3b : cyclic alkyl moieties having 5 to 12 carbon atoms, and \n R 3c : aryl moieties having 6 to 12 carbon atoms which are optionally alkyl substituted , \n and wherein the copolymer (A) has a weight average molecular weight M w  of 35,000 g/mol to 150,000 g/mol.
