BLENDS OF POLYPROPYLENE AND ELASTIC ALPHA-OLEFIN/CYCLE OLEFIN COPOLYMERS |
摘要 |
Blends of semi-crystalline polymers with rubbery thermoplastic copolymers are provided. The rubbery thermoplastic copolymers are elastic at temperatures above their Tg's and properties similar to thermoplastic elastomers and surface tensions 5 dynes/cm or more different, preferably greater than the surface tension of the semi-crystalline polymer. Improved properties include good elastic recovery, toughness, and high elasticity without significant loss in optical properties.
