  • Patent number: 9884439
    Abstract: A method for producing a foamed molded product includes: using a molding apparatus including a plasticizing cylinder having a high pressure kneading zone and a pressure reduction zone; and a screw; controlling a pressure of the pressure reduction zone to be a first pressure in a state that communication between the high pressure kneading zone and the pressure reduction zone is shut off, the first pressure being not less than an atmospheric pressure and not more than a maximum pressure of the high pressure kneading zone which is reached in a case that a molten resin is brought in contact and kneaded with a physical foaming agent; controlling back pressure of the screw to be a second pressure which is not less than the first pressure; and measuring a predetermined amount of the molten resin from which the gasified physical foaming agent has been separated.

  • Publication number: 20110020550
    Abstract: The present invention provides a method for allowing a metal complex to stably penetrate into a polymer and immobilizing the metal complex in the polymer by a low temperature treatment, in a batch processing for a plating pre-treatment wherein the metal complex is allowed to penetrate into the polymer with the use of high-pressure carbon dioxide. In particular, the present invention provides a method for producing a composite material containing a resin molded product, characterized in that a reducing agent is brought into contact with the resin molded product so as to allow the reducing agent to penetrate into the resin molded product, and in that high-pressure carbon dioxide having an organic metal complex dissolved therein is brought into contact with the resin molded product into which said reducing agent has penetrated, so as to immobilize the organic metal complex in the resin molded product by the reducing agent.
