Claims (1)

  1. Настоящее изобретение относится к способу получения полимеров и сополимеров олефинов CH2 = CHR, где R - атом водорода или алкильный или арильный радикал, имеющий от 1 до 10 атомов углерода, включающему по крайней мере одну стадию (со)полимеризации в газовой фазе, в присутствии высокоактивного катализатора, полученного из соединения титана с галоидом магния в активной форме в качестве носителя и алкильного соединения алюминия. Способ отличается тем, что он протекает при подаче маленького количества, относительно полимера, соединения, имеющего не менее двух групп, одинаковых или различных, способных вступать в реакцию с соединением алкилалюминия и избирательно подавлять реактивность частиц полимера, очень мелких по сравнению со средней гранулометрической величиной полимера, присутствующего в газовой фазе.
