Abstract
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.
