Abstract

A process for producing polyethylene resins containing carbon black in a gas fluidized bed reactor which comprises introducing into said reactor, polymerizable monomers capable of producing polyethylene resins at polymerizable reaction temperatures in the presence of a catalyst while directly introducing into said reactor during said polymerization, carbon black, in an amount to produce said polyethylene resins containing carbon black.
