Abstract
PROCEDIMIENTO DE OBTENCION DE COPOLIMEROS DE INJERTO RETICULADOS. SE REALIZA LA COPOLIMERIZACION DE PRECIPITACION DE UN 16-60 POR 100 EN PESO DE UN COPOLIMERO DE ETILENO-ESTER DE VINILO; POR EJEMPLO, ACETATO DE CINILO, COMO SUTRATO DE INJERTO DISUELTO EN TERC.-BUTANOL Y UN 85-40 POR 100 EN PESO DE UNA MEZCLA A INJERTAR COMPUESTA POR UN 93,9-48 POR 100 EN PESO DE UNO O VARIOS AROMATOS DE MONOVINILO, POR EJEMPLO, ESTIRENO, UN 5-30 POR 100 EN PESO DE ACRILONITRILO Y-O METACRILONITRILO, UN 1-10 POR 100 EN PESO DE UN AGENTE DE RETICULACION CONTENIENDO DOS O MAS ENLACES DOBLES C-C Y UN 0-1-12 POR 100 EN PESO DE OTRO MONOMERO COPOLIMERIZABLE, MONOOLEFINICAMENTE INSATURADO. PARA COMENZAR LA REACCION SE EMPLEA UN 0,3 A UN 0,5 POR 100 EN PESO, REFERIDO A LA MEZCLA DE MONOMEROS, DE UN INICIADOR SUMINISTRADOR DE RADICALES, POR EJEMPLO, PEROXIDICARBONATO ISOPROPILICO; AL MISMO TIEMPO SE AGREGA UN AGENTE DE PRECIPITACION, POR EJEMPLO, AGUA, QUE PRECIPITA EL SUSTRATO NOINJERTADO. SE EMPLEAN COMO MODIFICACORES DE LA RESISTENCIA AL IMPACTO, ESTABLES A LOS AGENTES ATMOSFERICOS PARA RESINAS CON REDUCIDA TENACIDAD.
