Abstract

LA INVENCION ACTUAL SE REFIERE A UN PROCESO PARA PRODUCIR UNA RESINA BASADA EN ESTIRENO DE GOMA MODIFICADA QUE COMPRENDE EL SUMINISTRO DE UNA SOLUCION DE UN MONOMERO BASADO EN ESTIRENO QUE CONTIENE DEL 5 AL 20 % DE SU PESO DE UN COMPONENTE DE GOMA QUE COMPRENDE UN COPOLIMERO BLOQUE BASADO EN ESTIRENO BUTADIENO QUE TIENE UN CONTENIDO DE ESTIRENO DEL 20 AL 50 % DE SU PESO PARA UNA PRIMERA ZONA DE POLIMERIZACION DONDE SE SOMETERA A POLIMERIZACION INICIAL HASTA QUE SU CONVERSION ALCANCE DEL 10 AL 30 % Y DESPUES, SUMINISTRAR LA SOLUCION DE LA POLIMERIZACION INICIAL HACIA UNA SEGUNDA ZONA DE POLIMERIZACION DONDE SE EFECTUARA LA INVERSION DE LA FASE MIENTRAS QUE AL MISMO TIEMPO EL AUMENTO DE LA CONVERSION DEL 30 AL 70 % PARA ASI POLIMERIZAR EL MONOMERO MIENTRAS SE CONTROLA EL DIAMETRO DE LA PARTICULA DE GOMA EN UNA GAMA DE 0.2 A 1.5 UM Y EN UN RADIO DE PROPORCION DE AREA DEL DIAMETRO DE LA PARTICULA DE GOMA/PROPORCION DEL NUMERO DEL DIAMETRO DE LA PARTICULA DE GOMA (DS/DN) A UN POCO MENOS DE 2.5.EL PROCESO PARA LA PRODUCCION DE UNA RESINA BASADA EN ESTIRENO DE GOMA MODIFICADA DE ACUERDO CON LA INVENCION ACTUAL ES FACIL PARA LA RETIRADA DEL CALOR DE LA POLIMERIZACION, DISMINUYE SU PODER DE AGITACION, ASI POR EJEMPLO: NO NECESITA UN APARATO DE ALTA RESISTENCIA. ADEMAS, ESTA RESINA OBTENIDA POR EL PROCESO DE LA INVENCION ACTUAL TIENE UNA RESISTENCIA DE ALTO IMPACTO Y UN BRILLO Y RIGIDEZ EXCELENTES; O SEA, QUE TIENE SUS PROPIEDADES FISICAS PERFECTAMENTE BALANCEADAS.
