Полученные сополимеры, например,бутадиена и этилена, имеют стереорегул рно св занные звень диенов в макроцепи.Цель изобретени — получение сополимеров с регулируемой микроструктурой и улучшенными свойствами.Дл этого предлагаетс использовать каталитическую систему, составленную из первого компонента А-алюмипийорганического соединени общей формулы АШз. где R — углеводородный радикал, выбранный из группы, включающей Ci—Cia, предпочтительно Ci—Cs, а еще более предпочтительно Са — Cg, алкил, циклоалкил, арил и аралкильные радикалы, и второго компонента В—титаноорганического -соединени , имеющего св зи Ti — X и Ti — OCOR, где R имеет указанное значение, а X — галоген в молекуле, или каталитической системы, составленной из первого компонента А — алюминийорганического соединени , имеющего общую формулу АГКз, где R имеет указанное значение, второго компо- 5 нента В — титаноорганического соединени , имеющего св зи Ti — X и Ti — OCOR, где R и X имеют указанные значени , структуру в молекуле и третьего компонента С — галогена, соединени галогена или их смеси. При10 этом получаетс высокомолекул рный чередующийс сополимер сопр женного диена и этилена, микроструктура сопр женного диена которого утрачивает стереорегул рность и в то же самое врем высокомолекул рный обо-15 гащенный этиленом неупор доченный сополимер сопр женного диепа и этилена. Отношение чередующегос сополимера к неупор доченному сополимеру в реакционном продукте может мен тьс в широком интервале регули-20 ровани условий полимеризации. Например, при уменьшении мол рного отношени сопр женного диена к этилену в первоначальной мономерпой композиции отношение чередующегос сополимера к неупор доченному сопо-25 лимеру в реакционном продукте уменьшаетс , и наоборот. Также отношение измен етс в соответствии с выбором используемой каталитической системы. Дл получени высокого отношени чередующегос сополимера к неу-30 пор доченному сополимеру в продукте реак- | |
