Control of heteroflocculation using a lower molecular weight fraction of the flocculant as a site blocking agent is demonstrated in the apatite-dolomite-polyethylene oxide system. The most effective SBA (site blocking agent) was determined to be the highest molecular weight fraction of the focculant
## Abstract Summary: The stoppedβflow polymerization of propylene catalyzed by a ZieglerβNatta catalyst in the presence of internal and external electron donors was carried out. The influence of the electron donors on the active sites of the catalyst was investigated using a multiple active site mo
