摘要:
A process for the production of EPM or EPDM comprising contacting ethylene, propylene, and, optionally, one or more dienes, in a fluidized bed, at a temperature at or above the sticking temperature of the product resin, under polymerization conditions, with a prepolymer, which is not sticky at the process temperature; a cocatalyst; and, optionally, a halocarbon promoter; and, optionally, an inert particulate material, wherein the amount of prepolymer or the combined amount of prepolymer and inert particulate material is sufficient to essentially prevent agglomeration of the fluidized bed and the product resin.
摘要:
A colorable resin particle having an outer shell of a non-sticky polymer and an inner core of a sticky polymer produced in a gas phase fluidized bed reactor at or above the sticking temperature of the sticky polymer using a non-sticky prepolymerized catalyst and processes for producing the colorable resin and the non-sticky prepolymerized catalyst.
