Abstract
869,370. Olefin polymerization. GELSENBERG BENZIN A.G. March 24, 1958 [March 22, 1957], No. 9422/58. Addition to 822,611. Class 2(6). A modification of the process described in the parent Specification comprising the dry or substantially dry polymerization of olefins utilizing a mass of polyolefin, e.g. polyethylene, as carrier for a Ziegler type catalyst complex, wherein each catalyst component, or solution thereof, is conveyed as a separate stream of gas, mist or vapour and each stream is brought into contact with the stirred mass of polyolefin, the catalyst being formed thereon and wherein a part of the final polymerisate of olefin produced is returned into the process to initiate a subsequent repetition of the process. The part returned may be sieved to produce a uniform fine particle size and may be wetted with a solvent, e.g. benzine, insufficiently for the powdery character to be lost. The ash content may also be reduced prior to returning the polyolefin carrier and the material may be divided into two portions, each being treated with a different catalyst component, before being remixed and returned. Specification 847,490 also is referred to.
