A manufacturing process for a material includes the steps of impregnating a predetermined amount of cellulose fibers with a predetermined amount of clay particulates, adding a predetermined amount of plastic, applying high heat to carbonize the combined materials and manipulating the combined materials while applying heat, and forming the carbonized combined materials by one of extrusion, casting, stamping, and as a 3-D printing filament

Provided are a biodegradable sheet with antiviral properties, a manufacturing method thereof, and the use thereof. The biodegradable sheet comprises: a biodegradable polymer resin consisting of a polylactic acid-based polymer; or a composite degradable polymer resin comprising of a biodegradable resin and a petrochemical resin; and particles of an inorganic antiviral agent or aggregated composite particles of at least two inorganic antiviral agents incorporated into the biodegradable sheet so that the inorganic antiviral agent can be dispersed with a particle size of 100 to 900 nm.

A process for the synthesis of a granular polymer, the process comprising (a) providing an active polymerization mixture that includes polymer, monomer, catalyst and optional solvent; (b) introducing a hydroxy-containing diaryl acetyl compound to the active polymerization mixture to thereby provide an inactive polymer mixture; (c) separating the polymer solution into a first stream and a second stream, where the first stream includes the polymer and the hydroxy-containing diaryl acetyl compound, and the second stream includes the monomer and the optional solvent; and (d) fabricating granules from the first stream.

The present invention relates to heterophasic polypropylene compositions comprising a propylene homo- or copolymer forming a crystalline fraction as a matrix and an amorphous propylene ethylene elastomer as a soluble fraction dispersed in said matrix. The heterophasic polypropylene compositions further comprise an elastomeric ethylene/alpha-olefin random copolymer. The heterophasic polypropylene compositions have a well-balanced relation between stiffness and impact strength, low volatile and semi-volatile emissions and good processability.
