    摘要： A twin screw extruder includes a barrel having a chamber, a discharge port, an extrusion molding die coupled to the discharge port of the barrel, axially extending first and second screw shafts, and a screw shaft support. The screw shaft support includes first and second spacer bearings disposed on the first and second screw shafts, and a first cross member including first and second loops slidably coupled to the first and second spacer bearings. A second cross member is spaced apart from the first cross member by a connection member, and also includes first and second loops slidably coupled to the first and second spacer bearings. The connection member is situated between the first spacer bearing and the second spacer bearing, and connected to the first cross member and the second cross member.

    摘要： A method for improving surface adhesion characteristics of a polymer substrate in which the portion of the surface of the polymeric substrate to be treated is contacted with a fluid material containing at least one oxidizing agent. The oxidizing agent in the fluid material is present in a kinetically degrading state capable of producing at least one chemical intermediate which is reactive with the polymeric substrate. Contact between the fluid containing the oxidizing agent and the polymeric substrate is maintained for an interval sufficient to produce or modify functional groups in the polymeric substrate proximate to its surface. The oxidizing agent of choice is a bivalent oxygen compound. The oxidizing agent is activated by an activator agent containing at least one carboxylic acid group or derivative thereof. The activator agent may be present in the fluid upon initial contact with the polymeric substrate or may be added to the fluid subsequent to initial contact with the polymeric substrate.

    摘要： A water-injection foaming devolatilizing method includes the steps of: melting and kneading a polymer in a water-injection dispersing zone of an extruder having a screw; injecting water into a polymer melt so as to be dispersed into the polymer melt which is being kneaded; and vaporizing volatile components contained in the polymer melt together with water in a devolatilizing zone having a vent port and located on a downstream side of the water-injection dispersing zone, so that the volatile components are removed and discharged through the vent port. A pressure-reducing expansion zone is provided between the water-injection dispersing zone and the devolatilizing zone so as to be upstream of the vent port. The method further includes gradually reducing a pressure in the pressure-reducing expansion zone so that not only bubbles in the water which is dispersed into the polymer melt are made to grow up, but also the bubbles are broken down at a downstream end portion of the pressure-reducing expansion zone.
