| 发明名称 | Peroxide treated metallocene-based polyolefins with improved melt strength | ||
| 摘要 | Disclosed herein are ethylene-based polymers having low densities and narrow molecular weight distributions, but high melt strengths for blown film processing. Such polymers can be produced by peroxide-treating a metallocene-catalyzed resin. | ||

| 主权项 | 1. An ethylene polymer having a ratio of Mw/Mn of less than or equal to about 5, a ratio of Mz/Mw of less than or equal to about 2.3, a zero-shear viscosity at 190° C. of greater than or equal to about 8×104 Pa-sec, a peak melting point in a range from about 100 to about 120° C., a vicat softening temperature in a range from about 95 to about 110° C., and a difference between the peak melting point and the vicat softening temperature of less than or equal to about 16° C. | ||
