    Abstract: A magnesium titanium olefin polymerization procatalyst is prepared by A) reacting a diorganomagnesium compound with a source of active chlorine, (with the proviso that the amount of chlorine is insufficient to completely convert the diorganomagnesium to magnesium dichloride); then B) removing unreacted diorganomagnesium from the reaction product; then C) adding a tetravalent hafnium species to the washed MgCl2 support; then D) depositing a tetravalent titanium species on the supported Hf. This procatalyst is highly active for the solution polymerization of olefins when combined with a cocatalyst.

    Abstract: A new P-N-P ligand is useful in ethylene oliogomenzation. The ligand is characterized by having at least one aromatic fiuorocarbyl alkoxide group bonded to a P atom, hi combination with 1) a source of chromium and 11) an activator such as methylalumoxane, the ligand of this invention may be used to prepare an oligomer product that contains a mixture of high purity alpha olefins, hi a preferred emobidment, the ligand of this invention enables a selective oligomerization in which the majority of the liquid product is a mixture of hexene and octene. The amount of byproduct polymer that is produced in preferred oligomerization reactions is advantegeously low.

    Abstract: An olefin polymerization catalyst is prepared by (a) in a diluent, combining a diorganomagnesium compound with less than 2 molar equivalents of a first source of chloride to produce a "chloride deficient" magnesium chloride support; (b) without isolating any solids, adding a second source of chloride which reduces the amount of soluble un-reacted diorganomagnesium compound present; (c) without isolating any solids present, adding a tetravalent titanium species and; (d) adding an activator. The catalyst is active for solution polymerization of olefins.

    Abstract: A continuous flow process for the oligomerization of ethylene using a chromium catalyst having a phosphorus - nitrogen - phosphorus ("P-N-P") ligand provides high selectivity to the desired tetramer (1-octene) with reduced production of coproduct C 10+ oligomers. Prior art processes that maximize catalyst activity have provided comparatively poor product selectivity. In particular, the production of larger amounts of C 10+ oligomers have been observed under conditions that maximize activity. The present process resolves this problem through the use of a combination of low catalyst concentration and by limiting the octene concentration in the reactor.

    Abstract translation: 使用具有磷 - 氮 - 磷(“P-N-P”)配体的铬催化剂使乙烯低聚的连续流动方法对所需的四聚体(1-辛烯)提供了高选择性,同时产生了副产物C10 +低聚物。 使催化剂活性最大化的现有技术方法提供了较差的产物选择性。 特别地,在活性最大化的条件下观察到产生更大量的C10 +低聚物。 本方法通过使用低催化剂浓度和限制反应器中辛烯浓度的组合来解决这个问题。
