Abstract
A process is provided for the stereospecific polymerization of an olefin such as ethylene in a liquid medium in which a finely-divided solid polymerization catalyst is fed to the polymerization zone on a truly continuous basis to provide a uniform dispersion of the polymerization catalyst throughout the polymerization zone. The process is carried out by pumping into the polymerization zone a Bingham fluid which has the finely-divided solid polymerization catalyst uniformly dispersed throughout a solid continuous phase, which is a mixture of a wax and a liquid hydrocarbon.
