The invention relates to oil formulation comprising Coils being stabilized for low temperature storage and preparation processes thereof. The invention also relates to the preparation of specific polymer compounds and their use as stabilizers for low temperature storage of Coils.

Vegetable oils with improved low temperature storage stability

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.

Process for preparing low sulfur dispersant polymers

The present invention describes a polymer useful as viscosity index improver comprising units derived from one or more ethylenically unsaturated ester compounds of formula (I), where R is hydrogen or methyl, Rmeans a linear, branched or cyclic alkyl residue with 1-6 carbon atoms, Rand Rindependently represent hydrogen or a group of the formula &#x2014;COOR', where R&#x2032; means hydrogen or a alkyl group with 1-6 carbon atoms, units of one or more ethylenically unsaturated ester compounds of formula (II), where R is hydrogen or methyl, Rmeans a 2-alkyl branched alkyl residue with 12-18 carbon atoms, Rand Rindependently are hydrogen or a group of the formula &#x2014;COOR&#x2033;, where R&#x2033; means hydrogen or an alkyl group with 12-18 carbon atoms, and units of one or more ethylenically unsaturated ester compounds of formula (III), where R is hydrogen or methyl, Rmeans a linear alkyl residue with 12-24 carbon atoms, Rand Rindependently are hydrogen or a group of the formula &#x2014;COOR&#x2033;, where R&#x2033; means hydrogen or an alkyl group with 12-24 carbon atoms wherein said polymer comprises at least 10% by weight units derived from one or more ethylenically unsaturated ester compounds of formula (I), based on the total weight of the polymer, said polymer comprises at least 10% by weight units derived from one or more ethylenically unsaturated ester compounds of formula (II), based on the total weight of the polymer, and said polymer comprises at least 10% by weight units derived from one or more ethylenically unsaturated ester compounds of formula (III), based on the total weight of the polymer.
