Abstract
PROCEDIMIENTO PARA LA OBTENCION DE POLIMEROS FUNCIONALES DE AZODICARBOXILATO. CONSISTE EN MEZCLAR UN POLIMERO, QUE TIENE FUNCION HIDROXILO, CON UN COMPUESTO DE FORMULA ZCO.N(H)<X.N(H)<X.COOR, EN LA QUE ZCO ES UN DERIVADO DE ACIDO REACTIVO CON RELACION A LOS GRUPOS HIDROXILO; X VALE 0 O 1; Y R PUEDE SER VARIOS TIPOS DE RADICALES. LA REACCION SE EFECTUA EN UN DISOLVENTE ORGANICO ANHIDRO, EN PRESENCIA DE PIRIDINA O QUINOLEINA. CUANDO X VALE 1, SE OXIDA EL GRUPO HIDRAZO DEL PRODUCTO A GRUPO AZO. ESTOS COMPUESTOS TIENEN APLICACIONES PARA LA OBTENCION DE COPOLIMEROS POR INJERTO DE UNA CADENA.
