ETHYLENE ALPHA-OLEFIN ELASTOMERIC POLYMER COMPOSITIONS HAVING IMPROVED EXTRUSION PROCESSIBILITY

摘要

Extruded shapes, profiles and parts in general based on an ethylene, alpha-olefin elastomeric polymer are manufactured utilizing a tailored approach to polymerization, leading to a polymer that delivers all of the benefits of metallocene based polymers, but without the drawbacks. Additionally, the ethylene, alpha-olefin elastomeric polymer has a broader molecular weight distribution than generally available from metallocene catalyzed elastomeric polymers.
