摘要： Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear .alpha.-olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected .alpha.-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected .alpha.-diimine nickel complexes with ethylene.
摘要翻译： 本文公开了聚合乙烯，无环烯烃和/或选择的环烯烃，和任选选择的烯属酯或羧酸和其它单体的方法。 聚合由选择的过渡金属化合物，有时是其他助催化剂催化。 由于一些聚合表现出活性聚合的某些特性，因此可以容易地制备嵌段共聚物。 所生产的许多聚合物通常是新颖的，特别是在它们的微结构方面，这给出了其中一些不寻常的性质。 公开了许多新颖的催化剂，以及一些制备它们的新方法。 制备的聚合物可用作弹性体，模塑树脂，粘合剂等。本文还描述了通过使用作为催化剂体系的乙烯低聚来合成线性α-烯烃，将具有选定的α-二亚胺配体的镍化合物和 选择的Lewis或布朗斯台德酸，或通过使选择的α-二亚胺镍络合物与乙烯接触。

摘要： Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear .alpha.-olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected .alpha.-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected .alpha.-diimine nickel complexes with ethylene.
摘要翻译： 本文公开了聚合乙烯，无环烯烃和/或选择的环烯烃，和任选选择的烯属酯或羧酸和其它单体的方法。 聚合由选择的过渡金属化合物，有时是其他助催化剂催化。 由于一些聚合表现出活性聚合的某些特性，因此可以容易地制备嵌段共聚物。 所生产的许多聚合物通常是新颖的，特别是在它们的微结构方面，这给出了其中一些不寻常的性质。 公开了许多新颖的催化剂，以及一些制备它们的新方法。 制备的聚合物可用作弹性体，模塑树脂，粘合剂等。本文还描述了通过使用作为催化剂体系的乙烯低聚来合成线性α-烯烃，将具有选定的α-二亚胺配体的镍化合物和 选择的Lewis或布朗斯台德酸，或通过使选择的α-二亚胺镍络合物与乙烯接触。
