the catalyst was easily isolated from the polymer solution. After regeneration, the recycled catalysts catalyzed the second run polymerization with similar or even higher activity and improved control. The residual catalyst concentrations in the polymers were in the range 50−100 ppm. The addition of a small amount of silica gel to the polymer solution could further reduce the residual catalyst concentration
