Abstract: The invention describes a process for overbasing a substrate comprising mixing the substrate, water, a phenol, a source of magnesium and a carbonating agent, wherein the water is retained throughout the overbasing reaction and provided further that the weight ratio of the water to the magnesium is in a 10:1 to 1:5 weight ratio, thereby obtaining a magnesium overbased substrate.

Abstract: A process for preparing a lower alkene polymer from a lower alkene feedstream, including the steps of: (A) contacting the lower alkene monomer with a catalyst system comprising boron trifluoride and at least one acid selected from the group consisting of sulfuric acid, sulfurous acid, phosphoric acids and strong acid resins and (B) polymerizing the lower alkene monomer in the presence of the catalyst system at a temperature of about -3 DEG C. to about -30 DEG C. thereby obtaining a lower alkene polymer having a molecular weight of about 250 to about 500.
