Abstract (en)
[origin: EP1881055A2] Terpolymer (I) of ethylene, at least an ethylenically unsaturated ester and propene, comprises: at least an ethylenically unsaturated ester derived structural units (12-16 mol.%); 1-4 propene derived methyl group per 100 aliphatic carbon atoms; and less than 6.5 chain ending methyl group per 100 methyl group. Independent claims are included for: (1) the preparation of terpolymer comprising reacting a mixture of ethylene, propene and at least a vinyl ester under increased pressure and increased temperature in the presence of a radical forming initiator, and then regulating the molecular weight by the addition of a moderator containing carbonyl group; (2) a composition (II) comprising at least (I) and at least a further different ethylene-copolymer; (3) a flowable additive concentrate with specific solidifying point of -10[deg]C comprising at least (I) (20-40 wt.%) for the improvement of flow characteristics, and at least a solvent (60-80 wt.%); (4) a process to improve the cold flow characteristics of a fuel oil comprising adding a formulation comprising at least 20 wt.% of at least (I), at or below 0[deg]C; and (5) a fuel oil comprising a distillate means and at least (I).
