具有阻燃剂性质的由酚酞衍生的苯并噁嗪化合物及其制备方法

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.
