The present invention provides, among other things, a process to produce a low molecular weight dispersant polymethacrylate polymer ('LMWDPMA'), and the LMWDPMA itself, along with the use of the LMWDPMA in a lubricating composition, as well as a method for lubricating an internal combustion engine as disclosed herein.

Well defined low molecular weight dispersant polymethacrylates

The invention provides a lubricating composition comprising a low viscosity base oil and a synergistic mixture of a functionalized ethylene-&#x3b1;-olefin copolymer, a poly(meth)acrylate polymer, and a metal-free anti-wear agent. The invention also provides a method of lubricating an internal combustion engine using such a lubricating composition.

Lubricating composition for and method of lubricating an internal combustion engine

The invention provides a lubricating composition comprising an oil of lubricating viscosity and synergistic mixture of a functionalized ethylene-&#x3b1;-olefin copolymer, a poly(meth)acrylate block polymer having a substantially oil soluble block and a substantially oil insoluble block. The invention also provides a method of lubricating a mechanical device using such a lubricating composition.

Lubricating composition containing a self-assembling polymethacrylate block copolymer and an ethylene-&#x3b1;-olefin copolymer

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&#x3b1;-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.
