Abstract
PROCEDIMIENTO PARA LA OBTENCION DE COPOLIMEROS DE INJERTO DE COPOLIMEROS DE ETILENO-ESTER DE VINILO, AROMATOS DE MONOVINILO Y (MET)-ACRILONITRILO MEDIANTE POLIMERIZACION DE PRECIPITACION. SE COPOLIMERIZA POR PRECIPITACION UN 10-80 POR 100 EN PESO DE UN COPOLIMERO DE ETILENO-ESTER DE VINILO COMO SUSTRATO DE INJERTO Y UN 90-20 POR 100 EN PESO DE UNA MEZCLA A INJERTAR DE UN 95-35 POR 100 EN PESO DE UNO O VARIOS AROMATOS DE MONOVINILO, UN 5-50 POR 100 EN PESO DE ACRONITRILO Y/O METRILONITRILO Y UN 0-15 POR 100 EN PESO DE UN MONOMERO COPOLIMERIZABLE, MONOOLEFINICAMENTE INSATURADO. PARA SU REALIZACION SE DISUELVE EL COPOLIMERO DE ETILENO-ESTER DE VINILO EN UN DISOLVENTE COMO LOS C4-C8-MONOALCOHOLES RAMIFICADOS Y DE CADENA RECTA. MEDIANTE LA ADICION DE LOS MONOMEROS Y DE UN INICIADOR RADICAL SE INICIA LA COPOLIMERIZACION DE INJERTO. SE AGREGA UN AGENTE DE PRECIPITACION COMO EL AGUA. DURANTE Y DESPUES DE LA PRECIPITACION SE SIGUEN AÑADIENDO LOS MONOMEROS Y EL INICIADOR Y TERMINADA LA ADICION SE COMPLETA LA POLIMERIZACION HASTA EL CONSUMO TOTAL DEL INICIADOR. SE EMPLEAN COMO TERMOPLASTOS ESTABLES A LOS AGENTES ATMOSFERICOS.
