  • Benzoxazine compounds derivated from phenolphthalein having flame-retardant properties and a process for their preparation
    Patent number: 9012543
    Abstract: The instant invention relates to 3,3?-bis(3,4-dihydro-3-phenyl-2H-1,3-benzoxazin-6-yl)-1(3H)-isobenzofuranone and analogues based on phenolphthalein, formaldehyde and a primary amine. Such compounds are, when cured to form polymeric networks, difficultly inflammable and resistant to high temperatures. Such compounds may especially be used in the production of printed wiring boards.
