Изобретение относитс к нефтехимиче ;к ..му синтезу, точнее - к полимеризации ( -олефниов.The invention relates to petrochemistry; to my synthesis, more precisely, to polymerization (α-olefnia.
Известен способ получени полиолефинов и л1нмеризацией tiL -олефинов в массе или в среде инертного углеводородного растворител iiini температуре 0-1ОО С в присутствии в качестве катализатора продукта реакции солей переходных металлов с металлоорганическиг .1И г;оединени ми в среде углеводородно U растворител . Этот способ имеет су1лественный недостаток, св занный с об зательным использованием органического ()азбавител на стадий приготовлени кат 1ЛИИ1Чьг:кой системы.A known method of producing polyolefins and l1nmerisation of tiL -olefins in bulk or in an inert hydrocarbon solvent iiini at a temperature of 0-1OO C in the presence as a catalyst of the reaction product of transition metal salts with organometallic .1and g; compounds in hydrocarbon-u solvent. This method has a serious disadvantage associated with the obligatory use of organic () a mincer in the preparation stages of the 1LII1CHi cat system.

Кроме того, взвеси катализатора в расчворнтеле не устойчивы и дл сохранени посто нства концентрации катализатора ьо всем объеме аппарата требуютс весг.ма эффективные перемешивающие устройства. In addition, catalyst suspensions in the dispenser are not stable, and to maintain a constant catalyst concentration in all the volume of the apparatus, weights and effective mixing devices are required.
