摘要：
The invention relates to a copolymer having high chemical uniformity, made of (A) 50 to 30 wt % of ethylene, (B) 50 to 70 wt % of C
4 - to C
24 -hydrocarbylester of (meth)acrylic acid, (C) 0 to 5 wt % of (meth)acrylic acid, and (D) 0 to 10 wt % of copolymerizable monomers that can be obtained by the polymerization of a mixture of 80 to 60 wt % of ethylene, 20 to 40 wt % of (meth)acrylic acid, and 0 to 10 wt % of copolymerizable monomers in a back mixing, continuously operating polymerization apparatus, and the subsequent polymeric analogous esterification of the copolymer thus obtained with C
4 - to C
24 -hydrocarbinols. The copolymer according to the invention is suitable for improving the cold flow properties of fuel oils, for reducing the lower mixing temperature of cold flow improving additives in fuel oils, and for improving the filterability of fuel oils containing cold flow improving additives.
