Abstract
A process for polymerizing monomers in the gas phase, in fluidized bed reactors is described, where unsaturated, gas phase monomers are fed into the reactors in the presence of a mixture of inert diluents having a composition that allows the dew point to be adjusted, this leading to high production rates under stable operation in a non condensed operation mode.
