A production method for a low molecular weight polymer suitable for a melt-blown non-woven fabric and a production device for melt-blown non-woven fabric, with which a high molecular weight polymer can be reduced in molecular weight by applying a shear force to the high molecular weight polymer without adding an additive. The low molecular weight polymer and the melt-blown non-woven fabric are produced using a continuous high shearing device that applies a shear force to the high molecular weight polymer serving as a raw material by rotation of a screw body to reduce the molecular weight of the high molecular weight polymer so as to obtain a low molecular weight polymer, and cools the low molecular weight polymer by passing the low molecular weight polymer through a passage arranged in the axial direction inside the screw body.

A fractional lobe processor comprises a barrel with heating and cooling means having two parallel intersecting bores of equal diameter, wherein the centre distance between the two bores is lesser than the diameter of the bore; a shaft coupled with a plurality of screw elements to form a screw within each bore, wherein the screws are intermeshing and form at least three zones within the barrel, the zones comprising an intake zone comprising at least one deep flighted shovel element on each intermeshing screw for receiving a feed comprising an active substance and/or an excipient, a melt zone consisting of only fractional lobe elements for melting the active substance and/or an excipient to form a viscous mass or melt, and a discharge zone, wherein the melt zone is located before the discharge zone and after the intake zone; and wherein the melt zone has a plurality of fractional lobe elements on each shaft.

Continuous processing equipment is suitable for use in the preparation of elastomeric compositions from end-of-life tire crumb or other vulcanized rubber starting materials. A reactor includes an outer barrel, a first shaft and a second shaft, and one or more piezoelectric transducer-driven acoustic horns arranged along the outer barrel and penetrating the outer barrel through a series of vibration-isolated ports which traverse a jacket of the outer barrel.

Rheology-modified, additive-containing ethylenic polymer compositions are prepared in a continuously operated extruder comprising first, second and third zones by a process comprising the steps of: mixing in the second zone of the extruder an ethylenic polymer and a high-temperature decomposing peroxide at a temperature such that the half-life of the peroxide is equal to or greater than (≥) one minute and for a sufficient period of time to modify the rheology of the ethylenic polymer to produce a rheology-modified, melted ethylenic polymer for transfer to the third zone of the extruder; and adding to the third zone one or more additives to the rheology-modified, melted ethylenic polymer to produce the rheology-modified, additive-containing ethylenic polymer.

A composite resin molded body includes a base compound resin and a molten-kneaded mixture which contains an organic fibrous filler, and a dispersing agent. In the composite resin molded body, a content of the organic fibrous filler is at least 5 mass % and at most 70 mass %, and a proportion T of the organic fibrous filler carbonized in the composite resin molded body is equal to or less than 0.1.

Provided are a carbon fiber composite material having high strength and elasticity and containing recycled carbon fibers, and a method for producing same. When a raw material is transported along the outer circumferential surface of a screw main body 37 having a passage 88 therein, the transport of the raw material is restricted by a barrier portion 82 provided on the outer circumferential surface, a shearing force is applied to the raw material by the screw main body 37, and a stretching force is applied to the raw material by passing the raw material from the inlet 91 of the passage 88 provided on the outer circumferential surface to the outlet 92 of the passage 88, thereby obtaining a carbon fiber composite material having good strength and elasticity and containing 50-70 wt % of recycled carbon fibers well dispersed therein.

A screw includes a screw main body, a conveyance portion conveying a raw material, and a passage provided in the screw main body. The passage includes a first passage element, a second passage element, and a third passage element. The screw main body has a plurality of cylindrical bodies arranged in an axial direction of the rotating shaft. At least a portion of the conveyance portion is formed on outer peripheral surfaces of the cylindrical bodies adjacent to each other, and the passage is formed in the cylindrical body so as to cross over between the adjacent cylindrical bodies.
