  • Patent number: 8440732
    Abstract: A foamable polymeric composition can comprise a polymer, a blowing agent cage material, and a blowing agent. The blowing agent cage material is selected from the group consisting of zeolite imidazolate framework, metal organic framework, carbon cage structure, and combinations comprising at least one of the foregoing. In one embodiment, the composition can be formed by mixing the polymer with the blowing agent cage material to form a mixture, introducing a blowing agent to the mixture, and forming the mixture into pellets.

  • Patent number: 7842379
    Abstract: Polymeric foams having nanocellular morphology are formed from a polymeric material having structural units derived from 2-hydrocarbyl-3,3-bis(hydroxyphenyl)phthalimidine compound. The foams include a plurality of cells having an average diameter of less than 1 micron. Processes for forming the foams include melting a polymeric material having structural units derived from 2-hydrocarbyl-3,3-bis(hydroxyphenyl)phthalimidine compounds; diffusing a blowing agent into the polymeric material to form a mixture; nucleating bubbles in the mixture is at a sufficient temperature and pressure to enable the production of cells having an average diameter of less than 1 micron; stabilizing the cells; and forming the mixture into a desired shape.
