DUAL CATALYST SYSTEM FOR PRODUCING LLDPE COPOLYMERS WITH IMPROVED PROCESSABILITY
Disclosed herein are ethylene-based polymers generally characterized by a density from 0.89 to 0.93 g/cm3, a ratio of Mw/Mn from 3 to 6.5, a Mz from 200,000 to 650,000 g/mol, a CY-a parameter at 190°C from 0.2 to 0.4, and a reverse short chain branching distribution. The ATREF profile of these poly...

| description | Disclosed herein are ethylene-based polymers generally characterized by a density from 0.89 to 0.93 g/cm3, a ratio of Mw/Mn from 3 to 6.5, a Mz from 200,000 to 650,000 g/mol, a CY-a parameter at 190°C from 0.2 to 0.4, and a reverse short chain branching distribution. The ATREF profile of these polymers can have a high temperature peak from 92 to 102°C, and a low temperature peak from 18 to 36°C less than that of the high temperature peak. These polymers can have comparable physical properties to that of a metallocene-catalyzed LLDPE, but with improved processability, shear thinning, and melt strength, and can be used in blown film and other end-use applications.
En la presente se describen polímeros a base de etileno generalmente caracterizados por una densidad de 0.89 a 0.93 g/cm3, una relación de Mw/Mn de 3 a 6.5, un Mz de 200,000 a 650,000 g/mol, un parámetro CY-a a 190 °C de 0.2 a 0.4, y una distribución inversa de ramificación de cadena corta. El perfil ATREF de estos polímeros puede tener un pico de alta temperatura de 92 a 102 °C, y un pico de baja temperatura de 18 a 36 °C menos que el pico de alta temperatura. Estos polímeros pueden tener propiedades físicas comparables a las de un LLDPE catalizado con metaloceno, pero con procesabilidad mejorada, dilución por cizallamiento y resistencia a la fusión, y pueden usarse en películas sopladas y otras aplicaciones de uso final. |
