Abstract
SE DESCRIBE UN METODO DE (CO)POLIMERIZACION RADICAL DE MONOMEROS DE VINIL ESTER, VINIL HALURO, DIENO, ACRILONITRILO, Y {AL}-OLEFINAS, OPCIONALMENTE CON UNO O MAS MONOMEROS ATILENICAMENTE INSATURADOS, CON UN INICIADOR DE POLIMERIZACION, EN PRESENCIA DE UNA CANTIDAD DE AL MENOS UN AGENTE DE TRANSFERENCIA DE CADENA DE PEROXIACIDO, QUE REDUCE DE MANERA EFECTIVA EL PESO MOLECULAR DEL (CO)POLIMERO EN COMPARACION CON EL DE UN (CO)POLIMERO OBTENIDO POR EL MISMO METODO, PERO SIN AGENTE DE TRANSFERENCIA. TAMBIEN SE DESCRIBEN (CO)POLIMEROS PRODUCIDOS A TRAVES DE DICHO METODO, Y LE UTILIZACION DE PEROXIACIDOS PARTICULARES COMO AGENTES DE TRANSFERENCIA EN LA POLIMERIZACION RADICAL DE UNO O MAS MONOMEROS ETILENICAMENTE INSATURADOS. ESTOS PEROXIACIDOS PROPORCIONAN UNA REUCCION CONSIDERABLE DEL PESO MOLECULAR, Y SON UTILES CON GRAN VARIEDAD DE INICIADORES DE POLIMERIZACION.
