According to the present invention an in-line compounding/extrusion deposition and molding apparatus and method of using the same are provided. The apparatus comprises a single step compounding and extrusion apparatus which includes an extruder screw. The apparatus includes a first zone, a second zone, and a third zone. The first zone is used to melt an inlet material before the screw advances the melted inlet material into the second zone which comprises a preparation and cutting zone. Simultaneously, as the inlet material is melted in the first zone, the screw rotation feeds a reinforcing fiber bundle into the second zone where the reinforcing fiber bundle is prepared for melt impregnation and is sheared to a desired length. While in the second zone, mixing begins between the melted inlet material and the sheared reinforcing fiber bundle. Next the mixture is advanced into the third zone for uniform distributive mixing and impregnation of the sheared reinforcing fiber bundle with the melted inlet material to form a fiber bundle filled melt.

Thermoplastic elastomeric compositions and processes for preparing the compositions comprising a blend of polypropylene, styrene-ethylene butylene-styrene copolymer, ethylene-propylene-diene monomer elastomer, linear low density polyethylene, peroxide crosslinking agent and a crosslinking coagent. The peroxide crosslinking agent and crosslinking coagent provide a crosslinking system. The compositions improve melt strength and increase resistance to flow and tear. The composition may further comprise mineral oil, antioxidant, colorant, a processing aid and stabilizer and mixtures thereof. The processes for preparing thermoplastic elastomeric compositions are particularly useful in microcellular injection molding to form articles with improved surface characteristics.
