ABSTRACT:
Large particle size polyolefin is obtained by polymerizing mono-olefins in the presence of a supported olefin catalyst which has been ball milled in the presence of small quantities of polytetrafluoroethylene (PTFE) powder in order to trap, i.e., entangle, the supported catalyst in a web of PTFE submicroscopic fibers.
