Abstract (en)

[origin: EP0406684A1] The invention relates to additives which have a deposition-preventing action on paraffin crystals and a flow-improving action in the case of middle distillates and which are based on ethylene/vinyl acetate copolymers built up from the components A) 20 - 95 parts by weight of an ethylene/vinyl acetate copolymer or an ethylene/vinyl acetate terpolymer having a specific viscosity of eta sp/c = 5 - 50 ml/g (measured at 25 degrees C in xylene), a vinyl acetate content of 25 -35 % by weight and a degree of branching of from 3 to 15 CH3 groups per 100 CH2 groups and B) 1 - 80 parts by weight of an ethylene/vinyl acetate copolymer having a melt viscosity index of from 20 to 1 000 g/10 mm and a vinyl acetate content of 15 -35 % by weight and C) 0 - 75 parts by weight of a polyalkyl (meth)acrylate having 6 to 26 carbon atoms in the alkyl radical. h
