  • Polymeric foam comprising low levels of brominated flame retardant and method of making same
    Patent number: 11447613
    Abstract: A composition and method for making polymeric foam is provided. The composition includes a flame retardant composition comprising brominated polymeric compounds. The resulting polymeric foams have a low bromine content of from about 0.01-0.5 wt. %, while maintaining acceptable flame retardant characteristics.
    Type: Grant

  • Liquid crystal polymer devices and materials
    Patent number: 6010641
    Abstract: Methods for loading and alignment of liquid crystal polymers in electro-optic and electro-active devices comprise in-situ polymerisation between substrates of monomer material in the presence of a cationic initiator. This allows for the synthesis of liquid crystal polymers containing polyether backbones.
