    摘要： A sulphur-free polymer comprising structural units of formula (I) and structural units of formula (II): wherein R 1 represents a C 8 to C 22 alkyl group, preferably a C 12 to C 16 alkyl group; wherein R 2 is hydrogen or methyl; wherein R 3 represents -R 5 (OR 6 ) n OR 7 ; wherein R 5 and R 6 may be the same or different and independently represent a linear or branched C 1 to C 8 alkylene group; wherein n is an integer from 1 to 20; wherein R 7 represents a C 1 to C 4 alkyl group; wherein R 4 is hydrogen or methyl; and wherein the molar ratio of structural units (I): structural units (II) in the polymer is in the range from 100:1 1 to 2:1. The polymers improve the low-temperature properties of fuel oils from petroleum sources, those from vegetable or animal sources, and mixtures of these fuel oils.

    摘要： A sulphur-free polymer comprising structural units of formula (I) and structural units of formula (II):


    wherein R 1 represents a C 8 to C 22 alkyl group, preferably a C 12 to C 16 alkyl group; wherein R 2 is hydrogen or methyl; wherein R 3 represents -R 5 (OR 6 ) n OR 7 ; wherein R 5 and R 6 may be the same or different and independently represent a linear or branched C 1 to C 8 alkylene group; wherein n is an integer from 1 to 20; wherein R 7 represents a C 1 to C 4 alkyl group; wherein R 4 is hydrogen or methyl; and wherein the molar ratio of structural units (I): structural units (II) in the polymer is in the range from 100:1 1 to 2:1.
    The polymers improve the low-temperature properties of fuel oils from petroleum sources, those from vegetable or animal sources, and mixtures of these fuel oils.
