Abstract: An apparatus for measuring and a method for controlling the static charge developed by a flowable solid as it passes through a conduit. The flowable solid is conveyed through the conduit in such a manner that the powder develops a static charge due to the triboelectric effect as it moves against the conduit walls. The static charge on the solid is then measured using a static charge measuring device such as a Faraday drum or cage.

Abstract: The invention relates to alteration of a linear low density polyethylene which is ordinarily free of long chain branching to introduce long chain branching into the polymer.

Abstract: A catalyst composition is described for preparing a high activity catalyst in silica which produces, in a single reactor, polyethylene with a broad or bimodal molecular weight distribution. The catalyst is prepared from the interaction of silica, previously calcined at 600.degree. C., with dibutylmagnesium, 1-butanol and titanium tetrachloride and a solution of methylalumoxane and ethylenebis[1-indenyl]zirconium dichloride.
