Claims (1)

  1. Способ газофазной полимеризации этилена и этиленовых смесей с альфа-олефинами CH2= CHR в присутствии высокоактивного катализатора, включающего в себя соединение титана, содержащее как минимум одну Ti-галогеновую связь, нанесенное на дихлорид магния в активной форме, причем названный способ включает следующие стадии: взаимодействие каталитического компонента; предполимеризацию этилена или этиленовых смесей с альфа-олефинами для получения полимера в количестве примерно 5 г на г твердого компонента, увеличенное до количества, соответствующего около 10% выхода конечного катализатора; полимеризацию этилена или этиленовых смесей с альфа-олефинами в газовой фазе в присутствии системы предполимер-катализатор при поддержании в газовой фазе молярной концентрации алкана между 20 и 90% по отношению к общему количеству газа.
