ORGANOPHOSPHORUS-NITROGEN COMPOUND WITH EXCELLENT FLAME RETARDANCY, A PREPARATION METHOD THEREOF, AND A FLAME RETARDANT COMPOSITION COMPRISING THE SAME

摘要

PURPOSE: An organophosphorus-nitrogen compound is provided to ensure excellent heat resistance and water resistance since a halogen element is not included and excellent fire retardant characteristic and stability since phosphorus and nitrogen are included at the same time.;CONSTITUTION: An organophosphorus-nitrogen compound has a structure of chemical formula 1. In chemical formula 1, A is NX1-NX2 or N=N; X1 and X2 are respectively hydrogen, C1-50 alkyl, C3-50 cycloalkyl, C6-50 aryl or heteroaryl groups of 5-50 nucleus atoms; and R1-R4 are respectively hydrogen, cyano, nitro, amino, thio, phosphoryl, phosphinyl, carbonyl, silyl, boranyl, C1-50 alkyl, C2-50 alkenyl, C2-50 alkynyl, C1-50 alkoxy, C3-50 cycloalkyl, C6-50 aryl, heteroaryl of 5-50 nucleus atoms, C6-50 aryloxy or C6-50 arylperoxy.;COPYRIGHT KIPO 2011
