    Abstract: A metallocene procatalyst useful in a catalyst system for the polymerization of olefins, particularly to make stereospecific polymers, and more particularly polymerization to make isotactic polypropylene is obtained from a process in which the product of a reaction between a suitable ligand and an alkali-alkyl is reacted with a transition metal salt in the presence of an accelerant that has at least one lone pair of electrons in its outer valence shell. When the metallocene procatalyst produced is used in a catalyst system for the production of isotactic polymers, specifically isotactic polypropylene, the metallocene procatalyst can be used without isolating and separating the racemic modification from the meso form.

    Abstract: A method for inhibiting polymer build-up in a recycle line and a heat exchanger during a polymerization process of one or more alpha olefins, particularly sticky polymers, or of one or more diolefins such as butadiene, isoprene, styrene, or styrene and butadiene, which method comprises introducing as an antifouling agent an alcohol having 1 to 20 carbon atoms, an alkyl or cycloalkyl ether having 2 to 20 carbon atoms, ammonia, an ester of an inorganic acid, a compound of a group IV element of the periodic table, alkyl and aryl amines, a sulfur-containing compound, or a mixture thereof at one or more locations in the recycle gas line in an amount sufficient to inhibit polymer build-up.

    Abstract: This invention is directed to processes for producing acyclic or cyclic alcohols or glycols, carbonyls, oxiranes or aziridines from hydrocarbyl group-containing compounds, particularly lower alkanes such as methane, ethane, propane or butanes, in which the hydrocarbyl group-containing compounds are converted under regioselective conditions to a functionalized ultimate precursor from which the final products can be produced. In its broadest sense, regioselective conditions are reaction zone conditions which are highly selective to the production and recovery of the desired functionalized compound, be it the ultimate precursor or an intermediate to the production of the ultimate precursor.

    Abstract: This invention relates to processes for producing one or more substituted or unsubstituted 1,6-hexanediols, e.g., 1,6-hexanediol, which comprise subjecting one or more substituted or unsubstituted alkadienes to hydrocarbonylation in the presence of a hydrocarbonylation catalyst, e.g., a metal-organophosphorus ligand complex catalyst, and a promoter and optionally free ligand to produce said one or more substituted or unsubstituted 1,6-hexanediols. The substituted and unsubstituted 1,6-hexanediols produced by the processes of this invention can undergo further reaction(s) to afford desired derivatives thereof, e.g., epsilon caprolactone. This invention also relates in part to reaction mixtures containing one or more substituted of unsubstituted 1,6-hexanediols as principal product(s) of reaction.
