摘要： Nonwoven fabrics and methods for making the same are described, wherein the fabrics comprise two or more propylene-based elastomers in combination with one or more propylene-based thermoplastic polymers. Specifically, the first propylene-based elastomer comprises at least 7% by weight ethylene or non-propylene alpha-olefin units, the second propylene-based elastomer comprises less than 7% by weight ethylene or non-propylene alpha-olefin units, the first and second propylene-based elastomers each have a heat of fusion less than 80 J/g, and the propylene-based thermoplastic polymer has a heat of fusion greater than 80 J/g.

摘要： Polymers made by transition metal catalyst systems comprising a bulky noncoordinating anion (NCA) as cocatalyst component. In comparison to polymers containing a conventional NCA, these polymers show a considerably lower dielectric loss, making them suitable for insulation applications such as for power cable.
