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 N?-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.

Abstract: This invention relates to novel salt compositions and to explosive compositions comprising said salt compositions. The salt compositions are useful as emulsifiers in the explosive compositions. The explosive compositions are water-in-oil emulsion explosives.

Abstract: Paraffin-containing liquid pour point depressants comprising the reaction product of a hydrocarbyl-substituted phenol and an aldehyde wherein: the olefin used in the preparation of the hydrocarbyl-substituted phenol has a high vinylidene content; the reaction between the hydrocarbyl-substituted phenol and the aldehyde is acid or base catalyzed; and/or the reaction further comprises phenol, are particularly useful for treating crude oils which have an initial pour point of 4° C. or higher, decreasing the fluid's pour point and improving the fluid's low temperature handling properties.
