Abstract: A catalyst composition and a process for preparing same comprising the reaction product of (a) an organometallic compound having the general formula R''nM, wherein n is an integer, at least one R'' is an alkyl group, an alicyclic group, or halogen or hydroxy or alkoxy radicals, or hydrogen, the remaining R'' groups are alkyl groups, alicyclic groups, alkaryl groups, aralkyl groups, aryl groups, or halogen or hydroxy or alkoxy radicals, and M is a metal of group II or group III of the periodic Table, (b) a co-catalyst component which is sulfur or a compound containing active hydrogen atoms, and (c) carbon dioxide. The catalyst composition is used in preparing copolymers of epoxy compounds with carbon dioxide.

Abstract: Strong reducing agents which are devoid of halogen atoms and certain silane compounds are used with supported bis(cyclopentadienyl)chromium (II) catalysts for the polymerization of olefins in order to obtain higher yields of polymer and allow for the use of supports which are activated at relatively low temperatures, and thus provide for a broader range of molecular weight distributions in the polymers made therewith.

Abstract: Ziegler-type hydrocarbon-soluble catalyst systems for the polymerization of conjugated diolefins, or mixtures thereof, to obtain high molecular weight polymers possessing varying proportions of trans-1,4 units, in the range of 50-90%. The catalyst systems are based on a nonreduced salt of titanium, an organometallic compound, and an iodine-containing compound, or iodine corresponding to the generalized formula Ti(halide)4-MnImAlRaX3 a. M is aluminum or tetravalent tin, n is 0 or 1, m is the valence of M and when n is 0, m is 2, X is Cl, Br or I, a is 2 to 3, R is alkyl, halide is Cl, Br or I and when halide is I, MnIm is omitted.

Abstract: This invention is an improved procedure for preparing a titanium halide-magnesium halide component of a Ziegler type catalyst. In the improved method a solution of titanium tetrachloride in an inert hydrocarbon solvent is mixed with magnesium chloride (or hydroxychloride) and an alcohol, with the provision that the titanium chloride solution is not mixed with the alcohol before contacting the magnesium chloride.
