Abstract
PROCEDIMIENTO PARA PREPARAR DERIVADOS DE FOSFORO Y NITROGENO CON EFECTOS IGNIFUGOS SOBRE POLIMEROS TERMOPLASTICOS. SE HACE REACCIONAR UN ACIDO DE FOSFORO CON UN DERIVADO HIDROXIALQUILO A TEMPERATURAS DE 140 A 260 C Y DURANTE UN TIEMPO DE 2 A 7 HORAS. EL DERIVADO HIDROXIALQUILO EMPLEADO, ES UN DERIVADO DE ACIDO ISOCIANURICO, DE MELAMINA O DE UREA. LOS ATOMOS DE NITROGENO Y LOS DE CARBONO SE ENTRELAZAN EN UNA ESTRUCTURA HETEROCIDICA. SE OBTIENE UN COMPUESTO N-(R)<N< -O-P DONDE R ES UN DERIVADO ALQUILENO Y N ES UN NUMERO DE 1 A 6.
