Estimating the term…
The present invention relates to materials useful for lowering the pour point of wax-containing mixtures of liquid hydrocarbons, as well as compositions of and methods for preparing the same. More particularly, this invention relates to the use in liquid hydrocarbons of OLAC compositions containing units derived from (i) hydrocarbyl(meth)acrylic acid derivatives and (ii) ethylenically unsaturated aliphatic Nα-olefin monomers having up to 50 carbon atoms. The OLAC compositions are useful for modifying the fluidity and flow characteristics of liquid hydrocarbons, and more particularly, for improving the pipeline pumpability of liquid hydrocarbons.
A composition comprising (a) at least one OLAC composition comprising a reaction product of (a)(1) at least one alpha olefin, and (a)(2) at least one hydrocarbyl(meth)acrylic acid derivative, and (b) a hydrocarbon solvent.
A method of depressing the pour point of a liquid hydrocarbon composition comprising adding to the liquid hydrocarbon composition an OLAC composition suitable to depress the pour point of the liquid hydrocarbon composition comprising a reaction product of (a1) at least one alpha olefin, and (a2) at least one hydrocarbyl(meth)acrylic acid derivative.
