Abstract
El objeto de la presente consiste en un proceso para poner en marcha una reaccion de polimerizacion de olefinas en fase gaseosa empleando un catalizadordel tipo Ziegler-Natta a base de un metal de transicion en un reactor de lecho fluidificado, a través del cual pasa una mezcla de reaccion gaseosa quecomprende la olefina, un gas inerte, hidrogeno y opcionalmente al menos un comonomero y que opera bajo condiciones de temperatura y presion que posibilitan lapuesta en marcha de la reaccion de polimerizacion, caracterizado porque la presion parcial de la olefina y la velocidad de introduccion de catalizador en elreactor se aumentan al tiempo que se mantienen constantes las relaciones de la presion parcial de la olefina a la presion parcial de hidrogeno y a la presionparcial de comonomero o comonomeros opcionales.
