    • In the polymerization of C3-C12-&agr;-olefins, the activity of the catalyst and the isotacticity and molecular weight of the polymer product can be adjusted and improved in a controlled manner by a new process wherein A) a catalyst system is prepared by bringing a support which comprises magnesium chloride, a derivative thereof or a reagent forming it into contact with at least titanium tetrachloride or a reagent forming it, in order to produce a titanated support; by bringing the titanated support into contact with at least a group 1, 2 or 13 metal compound which contains a C1-C10-alkyl and activates titanium tetrachloride to a catalytically active titanium group, in order to produce an activated support; and by bringing a substance selected from among the said support, titanated support and activated support into contact with at least one donor or a reagent forming it, in order to produce a catalyst system B) polymerization is carried out using the catalyst system by bringing it into contact with at least a C3-C12-&agr;-olefin, whereupon poly-C3-C12-&agr;-olefin chains are formed in the catalytically active titanium groups, and preferably by bringing the said catalyst system, the said C3-C12-&agr;-olefin and the said poly-C3-C12-&agr;-olefin chains into contact with hydrogen or some other similar chain transfer agent, whereupon a poly-C3-C12-&agr;-olefin terminated with hydrogen or suchlike is formed. In the process the improvement is achieved so that, in step A), i) a first controlled amount of a less soluble internal donor and a second controlled amount of a more soluble internal donor are provided on the surface of the said support, titanated support or activated support, in order to produce an internal donoration product, and ii) the internal donoration product is brought into contact with at least one eluant eluting the more soluble internal donor and with at least one external donor or a reagent forming it, in order to produce an external donoration product, the catalyst system thereby formed having at least catalytically active titanium groups, the said first controlled amount of the less soluble internal donor and the said second controlled amount comprising external donor.

    • The present invention relates to substantially pure poly(arylene ether), e.g. purities exceeding about 99%, and to a method for making the same. The method which eliminates multiple rinses with a complexing reagent includes removing the catalyst from the polymerization mixture by mixing the polymerization mixture with a complexing reagent and liquid/liquid centrifuging the multiphase mixture. Water is then added to the polymer phase prior to a subsequent liquid/liquid centrifuge process. Once the catalyst has been sufficiently removed, the polymer can be concentrated in a flash vessel (which is not heated) by introducing a heated polymer phase to the vessel at a high pressure and quickly reducing the pressure. The concentrated polymer can then be introduced to an extruder to produce the high purity polymer. Due to the introduction of low molecular weight poly(arylene ether) at the intake zone of the extruder, essentially pure poly(arylene ether) can be isolated by this process. By combining the extruder process with an underwater pelletizer, thus providing extremely rapid cooling of the polymer melt when it exits the extruder and contacts air, much better color and lower amount of black specs in the final product is obtained.
    • 本发明涉及基本上纯的聚(亚芳基醚),例如 纯度超过99%,以及其制造方法。 用络合剂除去多次冲洗的方法包括通过将聚合混合物与络合试剂和离心多相混合物的液/液混合来从聚合混合物中除去催化剂。 然后在随后的液/液离心分离工艺之前,将水加入到聚合物相中。 一旦催化剂已被充分除去,聚合物可以通过在高压下将加热的聚合物相引入容器而快速降低压力而将其浓缩在闪蒸容器(其不加热)中。 然后将浓缩的聚合物引入挤出机以制备高纯度聚合物。 由于在挤出机的入口区域引入低分子量聚(亚芳基醚),所以可以通过该方法分离出基本上纯的聚(亚芳基醚)。 通过将挤出机工艺与水下造粒机结合,从而在聚合物熔体离开挤出机并接触空气时提供非常快速的冷却,从而获得最终产品中更好的颜色和更少量的黑色规格。

    • A catalyst composition comprising (a) an iron-containing compound, (b) an organomagnesium compound and (c) a dihydrocarbyl hydrogen phosphite is disclosed for polymerizing 1,3-butadiene into syndiotactic 1,2-polybutadiene. The use of the catalyst composition of this disclosure avoids the use of environmentally detrimental components such as carbon disulfide and halogenated solvents. The melting temperature of the syndiotactic 1,2-polybutadiene can be varied from about 100 to about 190° C. by variations in the catalyst components and the component ratios. The ability to vary the melting temperature with a single catalyst composition is very desirable. The syndiotactic 1,2-polybutadiene can be used as a plastic or as an additive for rubber compositions wherein it can crosslink with conventional rubbers using conventional crosslinking agents.
