Micrometer-sized aggregates of polystyrene nanoparticles are presented as organic support materials for Ziegler–Natta catalysts. The catalytic activity in ethylene slurry polymerizations is found to be directly correlated to the hydroxyl group content of the supports. The ability to produce medium molecular weight distributions of high-density polyethylene in a one-pot, one-catalyst process in conjunction with good support fragmentability is demonstrated.
