Beschreibung
Zusammenfassung: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. L'invention procure des terpolymères d'éthylène, au moins un ester non saturé en éthylène et du propylène, lesquels a) contiennent 12,0 à 16,0 % en poids molaire d'unités structurales dérivées d'au moins un ester non saturé en éthylène, b) contiennent de 1,0 à 4,0 groupes méthyles dérivés de propylène par 100 atomes de carbone aliphatique et c) possèdent moins de 6,5 groupes méthyles issus de bouts de chaîne par 100 groupes de CH2, et également leur utilisation en tant qu'additifs froids pour des distillats moyens.
