摘要： Manufacture of particulate polyethylene by polymerizing ethylene in an agitated bed of dry particulate polyethylene by means of a catalyst system comprising (1) a particulate inorganic carrier and (2) a Ziegler catalyst applied to said carrier. The catalyst system is used in the form of an intimate mixture of the catalyst system with a particulate ethylene polymer which does not soften at the polymerization temperature used, the particles in said mixture being coated with a saturated hydrocarbon wax which is solid at 30*C but liquid at the polymerization temperature used. This process makes it possible to obtain particulate polyethylene having a desirable particle size distribution.

摘要： a process is provided in which a solid compound of a transition metal of Groups IVA to VIA is ground with at least one polymeric material containing sulphone groups and containing at least two repeat units of the formula:--Ar--SO.sub.2 --in which Ar is a bivalent aromatic radical and may vary from unit to unit in the polymer chain. The Ar radical preferably contains two aromatic rings linked together, as in: ##STR1## where X is an O or S atom, a direct link or the residue obtained by removing H from each --OH group present in an aromatic diol. If Ar varies the material is a copolymer. The polymeric material can be a polyethersulphone.The transition metal can be zirconium, vanadium or titanium. Preferably the transition metal compound is a halide such as titanium trichloride.

摘要： A method of producing a polymerization catalyst component suitable for use in the polymerization of alpha-olefins, which method comprises forming an active component by co-comminuting an inorganic Lewis acid, a first organic electron donor, a support base selected from the group consisting of the Group IIA & IIIA salts and the salts of the multivalent metals of the first transition series with the exception of copper, and a polymerization active tri-, tetra-, or penta-valent transition metal compound of a Group IVB-VIB metal, and heating the active component in an inert hydrocarbon solvent to produce the polymerization catalyst component. The active component can be heated in the inert hydrocarbon solvent in the presence of an additional polymerization active tri-, tetra-, or penta- valent transition metal compound of a group IVB-VIB metal. In addition, a second organic electron donor may be incorporated in the active component.

摘要： A transition metal compound and a metal halide compound are chemically combined to form a composition of matter. The composition of matter is mixed with a precipitating agent to form an active olefin polymerization catalyst. The catalyst can be further treated with a halide ion exchanging source to form an active olefin polymerization catalyst. Prepolymer is deposited on the catalyst(s) in an amount effective to reduce polymer fines when the catalyst(s) are used in polymerization processes.
