  • Patent number: 8236867
    Abstract: An embodiment of the present invention includes a method for chemically modifying inner surfaces of channels capable of further regulating characteristics of the internal environment of channels, by forming a polymer complex having a specific channel group B, the channel environmental characteristics of which are regulated by substituents A, followed by utilizing the channels of the channel group B as a reaction field to convert the substituent A to a different substituent. The method may comprise including a guest molecule in the channel of the channel group B in which the substituents A are arranged; and reacting the guest molecule with the substituent A in the channel to convert the substituent A to a substituent A?, and to arrange the substituent A? regularly directing to the inside of the channel of the channel group B or any channel of other channel groups.

  • Publication number: 20120065286
    Abstract: The present invention enables the secondary expansion of lightweight foamed beads. The foamed beads are produced using a compound comprising a compostable or biobased polyester and a physical blowing agent as well as a chemical blowing agent. Secondary expansion can be used either to lower the density of the foamed bead further or to enable expansion of the beads during molding to promote fusion. The foam beads can be produced using conventional melt processing techniques, such as single and twin-screw extrusion processes.

  • Publication number: 20120010311
    Abstract: A biodegradable two-liquid type foaming composition, which comprises main liquid and auxiliary liquid, is disclosed. The main liquid is formed by mixing polylactic acid powder, polycaprolactone polyol and foaming agent. The auxiliary liquid is formed by mixing polyol and isocyanate. Once the main liquid and the auxiliary liquid are mixed, the foaming reaction proceeds and the biodegradable foam is formed.

  • Patent number: 8026292
    Abstract: The present invention concerns a polycyanurate foam with a structural element A and either terminal amino groups and/or at least one of the following structural elements B, C, or D: wherein the foam has closed pores that contain carbon dioxide. This foam can be produced in that a substance is worked into the starting material for the polycyanurate that releases water or alcohol approximately at the start of polymerization either spontaneously or thermally or catalytically induced. The water/alcohol reacts with free cyanate groups under cleavage of CO2. The resulting amino groups can react further in the polymerization.
