摘要:
The present invention describes a composition comprising: (A) at least one polyalkyl (meth) acrylate polymer having a number average molecular weight Mn of from 15000 to 75000 g/mol; (B) at least one ethylene vinyl acetate copolymer comprising units being derived from at least one alkyl (meth) acrylate having 1 to 30 carbon atoms in the alkyl residue; (C) a phenolic type anti-oxidant; (D) a mixture stabilizer; and (E) a glycol ether solvent. The composition is useful as cold flow improver and oxidation stabilizer in vegetable oils and animal fats.
摘要:
The present invention relates to a process for preparing grafted polyalkyl(meth)acrylates (PAMAs) containing dispersant repeating units in the polymer backbone as well as in the grafted layer, which polymers are characterized by a low sulfur content, the products available by this process and their use as an additive to fuels, especially to middle distillates and blends thereof. The present invention further relates to a composition comprising the grafted polyalkyl(meth)acrylates prepared by the process according to the present invention and the use of said composition as an additive component to fuels, especially to middle distillates and blends thereof, and for improving the cold flow properties of fuel oil and fuel oil compositions, especially to middle distillate fuels and blends thereof.
