    摘要: A process for reducing draw resonance of a polymeric molten film susceptible to draw resonance under conditions which would cause draw resonance by extruding the film from a die and rapidly cooling said film in a rapid cooling zone containing a pressure roll and chill roll by providing a tensioning device between said die and the nip of said pressure and chill roll, said tensioning device providing a substantially friction free surface with respect to said moving film.

    摘要: The present invention includes a method for converting methane to methanol by providing a methane source to provide methane; contacting the methane with chlorine; exposing the methane to a light source to form methyl chloride; converting the methyl chloride with H20 to methanol and hydrochloric acid; converting the hydrochloric acid to chlorine; and purifying the methanol.The chemical cycle can be applied to the synthesis of alkane alcohols higher than methanol where appropriate.
