摘要： Catalyst residues of a transition metal compound and an organometalliccompound contained in a polymer slurry are deactivated by contact with anhydrous carbon dioxide. Preferably the contacting is carried out in a transfer line connecting the reaction zone with a zone of sufficiently lower pressure that flashing of diluent occurs in the transfer line to assure mixing of the carbon dioxide and the catalyst residues.

摘要： A silica-containing composition suitable for supporting chromium to produce a catalyst capable of giving high melt flow olefin polymers for such applications as injection molding and the like requiring a narrow molecular weight distribution, is produced by treating a silica-containing material at an elevated temperature with either (1) CO, (2) a bromine or iodine component, or (3) an oxygen-containing sulfur component, more specifically a carbon, oxygen and sulfur-containing component. Thereafter, anhydrous chromium can be added, for instance, by means of a hydrocarbon solution of a soluble chromium compound, and the resulting composition activated in air to produce a catalyst. The bromine or iodine treated silica contains bound bromine or iodine if the treating agent is HBr, HI, an organic halide of Br or I or elemental Br or I used in conjunction with a reducing agent. This material is a novel composition of matter and is suitable for use as a reinforcing agent in rubber or plastics and as a support for a chromatographic column in addition to being suitable for supporting a chromium compound to produce a catalyst.

摘要： High melt flow olefin polymers suitable for such applications as injection molding, and the like requiring a narrow molecular weight distribution are produced using a catalyst made by reducing and reoxidizing a chromium catalyst on either a titanium-silica cogel or a self-reduced silica-containing composition. In the first embodiment, a cogel formed by coprecipitating silica and titania, and containing a chromium compound, is treated in a nonoxidizing atmosphere, such as CO, hydrogen, N.sub.2 or a material decomposable to these materials, and thereafter reoxidized. In the second embodiment, a titanium-free chromium containing catalyst is first heated in air or the like to dry the catalyst and oxidize the chromium after which it is heated in an inert atmosphere wherein the composition is self-reduced to give chromium in a lower valence state. The resulting self-reduced composition is then heated in a reducing ambient and then reoxidized as in the first embodiment.
