In the coordinative polymerization of a-olefin by a slurry process, a low-dielectric-constant suspending agent, such as hexane or heptane, must be used. As a result of solvent movement and its friction between system components, electrostatic charges are generated. Because of low electrical conduction of these solvents, the generated charges accumulate in the polymerization medium. Consequently, a repulsive force between same charges effects the growth of the polymer particles and causes them to form fine particles. In this article, we present research results on the effects of antielectrostatic agents on the increase of the electrical conduction of the polymerization medium, particle size distribution, and also the quantity of fine particles in the final polymer. Techniques gained from the fuel industry were applied to modify the subjected polymerization medium. (c) 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
