The invention teaches a novel design for a fluidized bed polymerization reactor which utilizes a primary fluidization grid to provide mixing and fluidization of the polymer and at least one secondary distribution plate located above the first distribution plate to promote segregation of polymer particles by size, the larger particles falling into the lower fluidization zone and the smaller particles being entrained up from the primary fluidization grid and through the secondary distribution grid into an upper reaction zone.

Fluidized bed polymerization reactor with multiple fluidization grids

A method for the prevention of fouling of metallic surfaces exposed to reactive alpha-olefin gases during the production of polymeric resins which comprise coating such metallic surfaces with an amino silicone fluid and thereafter curing said coating by hydrolysis to form a continuous solid coating.

Process for reducing polymer build-up in polymerization equipment during

A process for reducing sheeting during production of polyolefins by polymerization of alpha-olefins utilizing titanium based polymerization catalysts wherein the static electric charges in the reactor at the side of possible sheet formation are maintained below static voltage levels which would otherwise cause sheet formation.
