ABSTRACT:
A process is provided for the continuous high-pressure mass polymerization of ethylene in which novel means are employed to continuously introduce the free radical generating polymerization initiator into the polymerization zone. The process is carried out by pumping into the polymerization a Bingham fluid which has a free-radical generating polymerization initiator uniformly dispersed throughout a solid continuous phase, which is a mixture of a wax and a liquid hydrocarbon.
