Abstract
The morphologies of three nascent high density polyethylene (HDPE) powders polymerized in the gas phase, were investigated using scanning electron microscopy. Different silicasupported catalysts were used for each of the polymers. The powders have globular, nodular and worm-like microstructures. The worm-like structures are comprised of extended chain cores and an overgrowth of folded chain lamellae. This dual morphology, which displays some similarities to a shish-kebab structure, arises from the shear during crystallization.
