MIDDLE DISTILLATES OF CRUDE OIL HAVING IMPROVED COLD FLOW PROPERTIES

摘要

Crude oil middle distillates with improved cold flow properties, containing small amounts of A. conventional flow improver on an ethylene base, and B. copolymers which consist to at least 70% by weight of one or a plurality of monomers of Formula I as well as II, R1 H2C=C-COOR2 and H2C=CH-O-R3 (I) (II) where R1 is hydrogen or methyl, R2 is a C8 to C18 alkyl, and R3 is a C18 to C28 alkyl and where the weight ratio of A to B is from 40 to 60 to 95 to 5.
