Abstract (en)
[origin: US4664676A] Additive compositions, useful in particular for improving the cold filterability properties of oil middle distillates, comprise: (A) at least one ethylene polymer; and (B) at least one polymeric compound resulting from the condensation of at least one compound comprising a primary amine group, of formula R-Z[(CH2)nNH]mH or HO-CH2-R''-NH2 wherein R is an alkyl from C1 to C30, Z is -NH-, -NR'- or -O-, R' being a C1-C30 alkyl, n an integrer from 2 to 4 , m an integrer from 1 to 4 (or zero when Z is -NH-), R'' is a C1-C18 alkylene, with a copolymer of a linear alpha -olefin, of an unsaturated alpha , beta -dicarboxylic compound and of an alkyl ester of an unsaturated monocarboxylic acid, or a vinyl ester of a saturated monocarboxylic acid. These additive compositions, used for example at concentrations from 50 to 500 g/m3, have a synergic effect on the filterability limit temperature of the middle distillates, particularly gas-oils.
