A process is provided for the polymerization of an olefin such as ethylene in the vapor phase in a moving bed of particles of the polymerized olefin in which novel means are employed to feed the finely-divided solid polymerization catalyst to 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 hydrocarbon which is a liquid at ambient temperature.
