Abstract

UN ARTICULO MOLDEADO DE UN POLIPROPILENO SINDIOTACTICO CON EXCELENTE TRANSPARENCIA EN EL QUE UN PUNTO DE FUSION, ATRIBUIDO AL POLIPROPILENO CON LA ESTRUCTURA SINDIOTACTICA, MEDIDO A UN PROMEDIO DE CALENTAMIENTO DE 10 C POR MINUTO MEDIANTE UN ANALISIS TERMICO DE EXPLORACION DIFERENCIAL, ESTA REPRESENTADO POR UN PUNTO MAXIMO UNICO, EL ARTICULO MOLDEADO ANTERIORMENTE DICHO SE PREPARA CALENTANDO, FUNDIENDO Y DESPUES MOLDEANDO POR CALOR UN HOMOPOLIMERO DE PROPILENO O UN COPOLIMERO DE PROPILENO Y UNA PEQUEÑA CANTIDAD DE OTRA OLEFINA, QUE TENGA UNA ESTRUCTURA PRINCIPALMENTE SINDIOTACTICA, O UNA MEZCLA DEL HOMOPOLIMERO O DEL COPOLIMERO Y UNA PEQUEÑA CANTIDAD DE UN POLIPROPILENO CON UNA ESTRUCTURA PRINCIPALMENTE ISOTACTICA, SEGUIDO POR EL APAGADO, O, TRAS ESOS PASOS, LA EXPOSICION ADICIONAL DEL ARTICULO MOLDEADO ANTERIOR A UN TRATAMIENTO DE CALOR A UNA TEMPERATURA INFERIOR A SU PUNTO DE FUSION. TAMBIEN SE REVELA AQUI UN METODO PARA PREPARAR EL ARTICULO MOLDEADO ANTERIOR.
