Abstract (en)
[origin: WO9400535A1] An additive for improving the cold flow properties of crude oil, lubricating oil or fuel oil comprises one or more oil-soluble copolymers of ethylene and an unsaturated monomer of general formula (I), wherein R6 is hydrogen or methyl, R5 is a -OOCR8 group wherein R8 is a hydrogen formate or a C1 to C28, more usually C1 to C17, and preferably a C1 to C8, straight or branched chain alkyl group, or R5 is a -COOR8 group wherein R8 is as defined above but is not hydrogen, and R7 is hydrogen or -COOR8 as defined above, and wherein (i) where there is more than one copolymer, the arithmetic mean of the content of said unsaturated monomer in the copolymers is below 11 mole %, or (ii) where there is one copolymer, the content of said unsaturated monomer in the copolymer is in the range of 6.5 to 10 mole %.
