  • Polymeric foams with nanocellular morphology and methods for making them
    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.
    Type: Grant
