Abstract: A non-volatile, anti-gel compound having a chain of at least about 5 repeat units of an alkylene oxide and which is soluble in olefin polymers, and an inorganic anti-block agent having a substantially neutral pH are added to a film grade transition metal catalyzed resin containing halide residues such as Ziegler-Natta catalyzed olefin polymer compositions to prevent: (1) gel streaking/pinstriping during film extrusion processes; (2) blocking of the extruded film; and (3) discoloration of the extruded film upon aging. The anti-gel compound has a molecular weight between about 200 and about 4,000,000 Daltons.
Abstract: This invention relates to certain 2,6-dioxocyclohexylidene-substituted heterocyclic compounds which show broad-spectrum herbicidal activity against a variety of broadleaf and grassy weeds.
Abstract: A process for reducing sheeting during production of polyolefins by polymerization of alpha-olefins utilizing titanium based polymerization catalysts wherein the static electric charges in the reactor at the site of possible sheet formation are maintained below static voltage levels which would otherwise cause sheet formation.
