A process for preparing in-reactor stabilized alpha olefin polymers comprising sequentially adding to a polymerization reactor
(i) a alpha-olefin monomer,
(ii) a selectivity control agent and olefin polymerization cocatalyst, separately, as a mixture or at least partially complexed,
(iii) an olefin polymerization procatalyst,
(iv) an alkyl aluminum compound as source of an antioxidant, and
(v) an acid acceptor and polymerizing the monomer.
The resulting polymer product is effectively stabilized and need not be compounded, in a separate energy intensive step, with an antioxidant.
一种制备反应器内稳定的α-烯烃聚合物的工艺,包括依次向聚合反应器中添加以下物质
(i) α-烯烃单体、
(ii) 选择性控制剂和烯烃聚合助催化剂,可单独、作为混合物或至少部分复配、
(iii) 烯烃聚合催化剂、
(iv) 作为抗氧化剂来源的烷基铝化合物,以及
(v) 酸接受体和聚合单体。
由此产生的聚合物产品得到有效稳定,无需在单独的高能耗步骤中与抗氧化剂复合。
