ADDITIVES FOR IMPROVING THE COLD PROPERTIES OF FUEL OILS

摘要

The invention provides terpolymers of ethylene, at least one ethylenically unsaturated ester and propene, which a) contain from 12.0 to 16.0 mol% of structural units derived from at least one ethylenically unsaturated ester, b) contain from 1.0 to 4.0 methyl groups derived from propene per 100 aliphatic carbon atoms, and c) have fewer than 6.5 methyl groups stemming from chain ends per 100 CH2 groups. and also their use as cold additives for middle distillates.
