Abstract
A particulated thermoplastic polymer having a uniform surface coating of zinc stearate is prepared by contacting the polymer particles with atomized droplets of molten zinc stearate while supporting and conveying the polymer by a moving stream of a gas. Reduced frictional forces allow increased volumes of coated particles to be transported by pneumatic conveyance. Substantially reduced fine particulate generation or "dusting" is observed for the composition.
