A colorable resin particle having an outer shell of a non-sticky olefinic polymer having a flow index of less than 20 decigrams/minute and an inner core of at least 90 wt % of a sticky polymer, the resin particle being made in a gas phase fluidized bed reactor at or above the sticking temperature of the sticky polymer in the absence of an inert particulate material fluidization aid.

Colorable non-sticky resin core-shell particles

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.
