Abstract (en)
[origin: EP0900836A1] The additive comprises a mixture containing either and/or ester as solvent agent. An additive to improve the flowability of paraffin-containing mineral oil distillate comprises a mixture containing an ethylene/vinylester co- or terpolymer and at least one paraffin disperser. The ether is of formula R-O-R', where R = 4-30C linear or branched alkyl or alkenyl groups and R' = 1-30C linear or branched alkyl or alkenyl groups. The ester is one or more CO(s) with 4-30C )oxygen residue) and one or more alcohol with 1-30C (alcohol residue). The ether and/or ester is/are cyclic, having a ring size of 6-30C. An Independent claim is also included for improving the flowability of mineral oils and mineral oil distillate.
