Abstract

SE REVELA UNA RESINA DE POLIMEROS AROMATICOS DE MONOVINILIDENO CON UNA DISTRIBUCION ESPECIFICA DEL TAMAÑO DE LAS PARTICULAS DE CAUCHO QUE PROPORCIONA COMBINACIONES SORPRENDENTEMENTE MEJORADAS DE PROPIEDADES DEL PRODUCTO, COMO PULIMENTO, RESISTENCIA A LOS IMPACTOS Y RESISTENCIA A LA TRACCION. DICHA RESINA TIENE UN PRIMER GRUPO DE PARTICULAS MAS PEQUEÑAS CON UN DIAMETRO DE VOLUMEN MEDIO DE LAS PARTICULAS DE 0,2 A 0,6 MICROMETROS Y UN SEGUNDO GRUPO DE PARTICULAS MAYORES CON UN DIAMETRO DE VOLUMEN MEDIO DE LAS PARTICULAS DE 2,5 A 5 MICROMETROS. EN ESTAS RESINAS ES ADEMAS NECESARIO, EN ESTA DISTRIBUCION ESPECIFICA DEL TAMAÑO DE LAS PARTICULAS DE CAUCHO, BASADA EN 100 PARTES DE PESO DEL CAUCHO O EQUIVALENTE DE CAUCHO, QUE (A) LAS PARTICULAS QUE CONSTITUYEN 20 A 60 PARTES DE PESO DEL CAUCHO TENGAN DIAMETROS DE 0,1 A 0,8 MICROMETROS, (B) LAS PARTICULAS QUE CONSTITUYEN 60 A 20 PARTES DE PESO DEL CAUCHO TENGAN DIAMETROS DE 2 A 6 MICROMETROS, Y (C) QUE HAYA UNA CANTIDAD ESPECIFICA DE PARTICULAS DE TAMAÑO INTERMEDIO QUE CONSTITUYAN DE 10 A 30 PARTES DE PESO DEL CAUCHO Y QUE TENGAN DIAMETROS ENTRE 0,8 Y 2 MICROMETROS. TAMBIEN SE REVELA UN PROCESO PARA LA PREPARACION DE DICHAS RESINAS EN UN PROCESO DE PRODUCCION SIMPLIFICADO EN DONDE EL CAUCHO QUE SE UTILIZA TIENE DISTINTOS COMPONENTES DE PESO MOLECULAR ALTO Y BAJO, TENIENDO EN CUENTA QUE EL COMPONENTE DE PESO MOLECULAR ALTO TIENE UN PESO MOLECULAR MEDIO DE AL MENOS DOS VECES Y MEDIA MAYOR QUE EL DEL COMPONENTE CON PESO MOLECULAR BAJO.
