Evaluation of newly copolymers and their montmorillonite nanocomposite as cold flow improver for petroleum lubricating oil.

The great demand on the energy makes the attention toward modifying lubricating oil. This work tends to prepare the following copolymers; octadecylmethacrylate-co-dodecene (CP) and octadecylmethacrylate-co-hexadecene (CP) by free radical solution polymerization using laboratory prepared octadecylmethacrylate monomer with either 1-dodecene or 1-hexadecene. The same monomers also used to prepare their polymers nanocomposite (NP, NP) with 1% of nanomontmorolonite by emulsion polymerization.
