A process for producing polymer in a gas phase reactor by introducing a stream of monomer and gas into a polymerization zone while providing at least one liquid component in the polymerization zone.

Gas phase polymerization process

A process for controlling the molecular weight (Mw) and molecular weight distribution (MWD) of polybutadiene polymerized in an otherwise gas phase process using a rare earth catalyst is provided.

Molecular weight control of gas phase polymerized polybutadiene when using a rare earth catalyst

Permeable membranes comprised predominantly of specifically defined tetrabromobisphenols and aromatic dicarboxylic acids. The invention also pertains to the novel permeation processes for recovery of an oxygen/nitrogen or carbon dioxide/methane component form a mixture of said component with other components.

Semipermeable membranes based on specified tetrabromobisphenol type

Permeable membranes comprised predominantly of specifically defined polyester of 4,4'-(1H-alkylidene)bis[2,3,6-trialkylphenol] and aromatic dicarboxylic acids. The invention also pertains to the novel permeation processes for recovery of an oxygen/nitrogen or carbon dioxide/methane or helium/methane component from a mixture of said component with other components in the mixture.
