The invention provides a process for preparation of a polyethylene nanocomposite comprising dispersing a base polyethylene resin and planar carbon nanoparticles in an inert liquid at conditions under which the base polyethylene resin is not solubilised in the inert liquid, and removing an amount of the liquid sufficient to provide a dispersion of the planar carbon nanoparticles in the base polyethylene resin.

Process for preparation of polyethylene nanocomposite

A polyethylene nanocomposite composition comprising: (i) base polyethylene resin of medium density polyethylene or high density polyethylene resin having a melt flow index in the range of from 0.10 to 1.4 g/10 min at 190&#xb0; C. and 5 kg as measured according to ISO 1133, high load melt flow index of from 4 to 20 g/10 min at 190&#xb0; C. and 21.6 kg as measured according to ISO 1133 and a density in the range of from about 0.930 to about 0.970 g/cmat 23&#xb0; C. as measured according to ASTM D792; and (ii) planar carbon nanoparticles having a BET (from Brunauer-Emmett-Teller (BET) theory) surface area of at least 50 m/g, in an amount of from 0.1% to 20% by weight based on the weight of the polyethylene nanocomposite composition.

Polymer resin composition and articles formed with the composition

The present invention relates to a method and apparatus for controlling static charges in a fluidized bed olefin polymerization reactor. Static charges which develop in the polymer products are measured and, if they fall outside a predetermined range, static charge control agents are introduced into the reactor. By controlling the static charges in the reactor, sheeting and drooling can be controlled.
