Abstract

PROCEDIMIENTO PARA LA PREPARACION DE COPOLIMEROS DE BLOQUES A BASE DE PIVALOLACTONA, PARTICULARMENTE DEL TIPO AX BY CZ, EN DONDE AX ES UNA SECUENCIA POLIVINIL O POLIISOPROPENIL AROMATICA; BY ES UNA SECUENCIA DIENICA Y CZ ES UNA SECUENCIA POLIPIVALOLACTONICA, SIENDO X, Y, Z NUMEROS ENTEROS QUE REPRESENTAN LA UNIDADES DE MONOMERO EN LAS RESPECTIVAS SECUENCIAS. COMPRENDE LAS SIGUIENTES ETAPAS: 1) SE POLIMERIZA EL MONOMERO VINIL O ISOPROPENIL AROMATICO; 2) SE AÑADE EL DIENO AL PRODUCTO FORMADO EN LA ETAPA ANTERIOR; 3) SE FUNCIONALIZA EL POLIMERO VIVIENTE OBTENIDO EN LA SEGUNDA ETAPA CON GRUPOS CARBOXILICOS, HACIENDO REACCIONAR INICIALMENTE DICHO POLIMERO VIVIENTE CON ANHIDRIDO CARBONICO Y LIBERANDO SUCESIVAMENTE LA FUNCION CARBOXILICA POR TRATAMIENTO ACIDO; Y POR ULTIMO, SE AÑADE PIVALOLACTONA AL POLIMERO OBTENIDO EN EL TERCERA ETAPA.
