Abstract

The present invention relates to a composition of additives comprising: at least one first compound selected from: (i) copolymers of ethylene and vinyl acetate having a molar mass Mn included in the range ranging from 10,000 to 60,000 g·mol−1, optionally grafted by at least one alkyl (meth)acrylate group, the alkyl chain of which is saturated and contains from 12 to 30 carbon atoms; and (ii) polymers comprising at least 90 mol % of units derived from alkyl. (meth)acrylate monomer, the alkyl chain of which is saturated and contains from 18 to 22 carbon atoms; and at least one second compound selected from the modified alkylphenol-aldehyde resins. The invention also relates to the use of this composition of additives for lowering the viscosity of a liquid petroleum product such as a crude oil and for reducing the deposition of paraffins.
