Abstract

A polymerization and/or copolymerization process in gas phase and in fluidized bed of ethylenically unsaturated monomers, according to which it is operated in the presence of one or more catalysts or initiators and a solid substance, characterized in that the lower part of the reactor carries a a decreasing section element provided at its base with a grid, the surface of the lower section of said element being 1.5 to 20 times smaller than the surface of the section of the main element of the reactor.
