Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE POLIETERES DERIVADOS DE OXETANOS, POR POLIMERIZACION CATIONICA (CASI-VIVA), PARTICULARMENTE PARA LA PRODUCCION DE PREPOLIMEROS TERMINADOS EN HIDROXI, APROPIADOS PARA UTILIZARSE EN REACCIONES DE CURADO CON ISOCIANATOS PARA PRODUCIR ELASTOMEROS. EL PROCEDIMIENTO IMPLICA LA ADICION CONTINUA DURANTE PERIODOS DE 12-50 HORAS DE UN MONOMERO DE OXETANO A UNA MEZCLA DE REACCION QUE CONSTA DE UN INICIADOR DEL TIPO DE DIOL Y UN CATALIZADOR CAPAZ DE CATALIZAR LA POLIMERIZACION CATIONICA <CASI-VIVA> DEL MONOMERO, SIENDO LA VELOCIDAD DE ADICION TAL QUE EL CATALIZADOR ESTE SIEMPRE EN UN EXCESO ESTEQUIOMETRICO CON RESPECTO AL MONOMERO. LA TERMINACION DE LA POLIMERIZACION ES EFECTUADA MEDIANTE LA ADICION DE SALMUERA. BAJO ESTAS CONDICIONES, SE PRODUCEN POLIMEROS DE PESO MOLECULAR INCREMENTADO Y CON NIVELES REDUCIDOS DE IMPUREZAS.
