Olefins are polymerized under solution polymerization conditions in the presence of the solid catalytic product resulting from removing the liquid components from the product resulting from admixing in an inert diluent and in an atmosphere which excludes moisture and oxygen (A) at least one hydrocarbon soluble organomagnesium compound; (B) at least one organic hydroxyl-containing compound; (C) at least one reducing halide source; (D) at least one transition metal (Tm) alkoxide.

Catalyst and process for polymerizing olefins

A process for blanking a reaction mixture utilizing as a blanking agent a difunctional lithium composition.

Blanking process for reaction mixture

A transition metal-containing catalyst is prepared by

Transition metal containing catalyst

The inactive palladium-containing precipitate formed during the reaction of a carboxylic acid and an olefin to form an ester can be reactivated by the addition of a suitable reducing agent to a slurry of the precipitate in the ester.
