发明名称 BENZOXAZINE COMPOUNDS DERIVATED FROM PHENOLPHTALEIN HAVING FLAME-RETARDANT PROPERTIES AND A PROCESS FOR THEIR PREPARATION
摘要 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.
