摘要： The present invention relates to an apparatus for gas phase polymerisation of olefins(s), essentially comprising a fluidized bed reactor and at least one conduit for drawing off polymer provided with an isolation valve and connecting the vertical side wall of the reactor to a lock hopper, the said conduit leaving the vertical side wall of the reactor while being directed downwards so that each part of the said conduit forms with a horizontal plane an angle A ranging from 35° to 90°. It also relates to a process for continuous gas-phase polymerisation of olefin(s) in a fluidized-bed reactor, comprising drawing off the polymer from the vertical side wall of the reactor into a lock hopper via a draw-off conduit so that all flow of the polymer in the draw-off conduit is produced according to a downward direction forming with a horizontal plane an inclination with an angle A at least equal to the angle of repose β of the polymer and not exceeding 90°. The present invention improves the degree of filling of the lock hopper and reduces the amount of gas drawn off with the polymer.

摘要： This invention relates to a liquid phase process for the cationic polymerization of C₄ hydrocarbon feedstreams comprising isobutene in the presence of a Friedel-Crafts catalyst to a polybutene having a number average molecular weight of 600-7000. In the process, the feedstream is pre-treated with an alkyl halide, eg tertiary butyl chloride, in the substantial absence of any hydrogen halide prior to contact with the Friedel-Crafts catalyst. The polybutenes produced by this process can be used to produce functionalised derivatives which in turn can be used as additives in lubricating oils.
摘要翻译：本发明涉及一种用于在Friedel-Crafts催化剂存在下的异丁烯与数均分子量为600-7000的聚丁烯的C4烃原料流的阳离子聚合的液相方法。在该方法中，在与Friedel-Crafts催化剂接触之前，基本上不存在任何卤化氢，用烷基卤，例如叔丁基氯预处理进料流。通过该方法生产的聚丁烯可以用于制备官能化的衍生物，其又可以用作润滑油中的添加剂。

摘要： Catalyst compositions comprising metallocene complexes having polymerisable groups may be used for the preparation of polyolefins.
The catalyst compositions may be in the form of polymers comprising the metallocene complex and may be suitably supported on inorganic supports. Polymers having a broad range of density and melt indices as well as low hexane extractables and excellent powder morphology and flowability may be obtained by use of the catalyst compositions. Preferred metallocene complexes are zirconium complexes in which the polymerisable group is vinyl.

摘要： Process for the polymerisation of ethylene or the copolymerisation of ethylene and at least one higher olefin comprising 3 to 12 carbon atoms. The process involves the use of an activated chromium catalyst on a refractory oxide support together with an organo metallic compound of a metal selected from the group consisting of magnesium, boron and zinc.
The process enables polymers of higher density to be produced compared with those obtained with conventionally used organo-metallic compounds. The catalyst used also tends to reduce fouling and agglomeration in a gas phase reactor.

摘要： The present invention relates to a process for manufacturing in a gaseous phase a polyolefin, preferably a copolymer of ethylene containing from about 1% to less than 30% by weight of at least one alpha-olefin comprising 3 to 8 carbon atoms, in the presence of a Ziegler-Natta catalyst system comprising (1) a solid catalyst and (2) a cocatalyst based on at least one organometallic compound. The solid catalyst is obtained by contacting (a) a vanadium compound and a titanium compound with (b) at least one organometallic compound capable of reducing the said vanadium and titanium compounds and with (c) a support containing magnesium dichloride free from any Mg-C bond and an electron-donor compound, D1, free from labile hydrogen, the said support consisting of spheroidal particles having given sizes and a narrow particle size distribution. Prior to its contact with (a) and (b), the support is preferably contacted with at least one electron donor compound, D2, containing labile hydrogen. The ethylene (co)polymer is directly obtained in the form of a dry powder consisting of spheroidal non-adhesive particles.
