Abstract

METODO PARA LA PREPARACION DE POLIMEROS DE ALMIDON INJERTADO CON POLIACRILAMIDA Y FUNCIONALIZADO, SOLUBLE EN AGUA, QUE TIENE APLICACIONES COMO ADITIVO PARA PAPEL DE RESISTENCIA EN HUMEDO. COMPRENDE LA REACCION DE POLIMERIZACION DE ALMIDON DEGRADADO CONVERTIDO CON ENZIMA Y ACRILAMIDA, EN PRESENCIA DE UN INICIADOR DE POLIMERIZACION POR RADICALES LIBRES, PARA PRODUCIR UN POLIMERO CONSTITUIDO POR UNA CADENA PRINCIPAL DE ALMIDON E INJERTOS DE POLIACRILAMIDA, QUE TIENE POR LO MENOS 5% DE POLIACRILAMIDA; Y FUNCIONALIZAR DICHBO POLIMERO CON SUSTITUYENTES DERIVADOS DE UNO O MAS MATERIALES QUE CONTIENEN DOS O MAS UNIDADES DE ALDEHIDO, TALES COMO GLIOXAL, GLUTARALDEHIDO O ALDEHIDOS DEL ACIDO CIANURICO, EN CANTIDAD SUFICIENTE PARA QUE LA PROPORCION DE POLIMERO A SUSTITUYENTES SEA 1:1 A 20:1.
