Procedure

The resultant product contained 24.64 percent by weight of a 1:2 copolymer of stearyl methacrylate (SMA) and methacrylic acid (MAA), 0.61 percent residual SMA; less than 0.02 percent residual MAA; no initiator; less than 0.05 percent 2-mercaptoethanol; and had a bulk viscosity at 25° C. of about 4000-5000 centipoise. When the product was diluted to 10% polymeric solids with further oil, the solution had a viscosity at 25° C. of 36-46 centipoise.
