Abstract

SE PRESENTAN COMPOSICIONES DE RESINA DE POLICARBONATO QUE CONTIENEN (A) 100 PARTES DE POLICARBONATOS PREFERIBLEMENTE QUE TENGAN UN PESO MOLECULAR DE VISCOSIDAD MEDIA DE ENTRE 12,000 Y 18,000 Y (B) ENTRE 0.01 Y 5 PARTES DE OLIGOMEROS DE (ALFA)-OLEFINA, EN DONDE LOS POLICARBONATOS SON LOS PRODUCTOS DE LA POLIMERIZACION EN ESTADO FUNDIDO DE DIHIDROXIDO AROMATICO DE DIESTERES DE CARBONATOS. ESTAS COMPOSICIONES DE RESINA SE CARACTERIZAN POR SU BUENA LIBERACION DEL MOLDE Y SU ESTABILIDAD TERMICA, Y POR SUFRIR UNA MUY PEQUEÑA DECOLORACION O DESCENSO DEL PESO MOLECULAR DURANTE EL PROCESO DE MOLDEADO.
