Abstract

A support containing methylaluminoxane and derivatives thereof is formed by an incipient impregnation of a silica support so that the solution of the aluminoxane fills the pores in the support with no solution left out. The supported aluminoxane eliminates the problem of fluid bed reactor fouling during gas phase polymerization of olefins in the presence of added metallocenes. The fluid bed reactor (10) is a vertical enclosure with a reaction zone (12), comprising a bed of growing polymer particles and a minor amount of catalyst particles fluidized by the continuous flow of polymerizable and modifying gaseous components, a velocity reduction zone (14), where entrained particles are given opportunity to drop back into the fluidized bed, and a distributor plate (20). The unreacted gas passes through a cyclone separator (22), a filter (24), a compressor (25) and a heat exchanger (26). The distribution plate (20) serves the purpose of diffusing recycle gas through the bed at a rate sufficient to maintain fluidization.
