    摘要： The present invention relates to a method and an apparatus for producing tyres. The apparatus comprises a mixing extruder (1) including a suction pump (24) in fluid connection with an inner chamber (17) of the mixing extruder (1) at a sector of the mixing extruder (1) close to an extruder head (19), such a suction pump (24) being suitable to operate at a suction pressure (Pa) preferably lower than about 150 mbars. This suction pressure enables the processing ability features of the elastomeric compound, as well as the performances findable in a tyre obtained from semimanufactured products produced with said elastomeric compound, to be improved.

    摘要： A customizable polyamide polymer, in particular Nylon 66, Nylon 6, and copolyamides, having a high molecular weight, excellent color, and low gel content is disclosed. In particular, disclosed is a polymer having a relative viscosity greater than 50 as measured in a 90% strength formic acid solution; consistent viscosity with a standard deviation of less than 1; a gel content no greater than 50 ppm as measured by insolubles larger than 10 micron; an optical defect content of less than 2,000 parts per million (ppm) as measured by optical control system (OCS). The polymer can be made into monofilaments or a multifilament yarn. Also disclosed is a process of producing the polymer using in-line vacuum finishing technology in the absence of steam or other gases in the second, or post condensation, step of the polymer process.

    摘要： Processes for decrosslinking crosslinked plastic and devulcanizing vulcanized rubber include advancing such materials through single screw or twin screw extruders including special ultrasonic treatment zones wherein threadless shaft (single screw) or shafts (twin screw) rotate under an ultrasonic horn having a distal end aligned with the shaft or shafts and being shaped complimentary thereto. Special arcuate (single screw) or double-arcuate ultrasonic treatment flow paths confine the materials to flow under the horn where the material is subjected to ultrasonic waves to decrosslink the material, in the case of crosslinked plastic, or devulcanize the material, in the case of vulcanized rubber, with the extrudate leaving the die as a continuous stream or rope as is typical of virgin plastic or rubber.
