Title:
THERMOPLASTIC ELASTOMER AND MOLDED OBJECT THEREOF
Document Type and Number:
WIPO Patent Application WO/2004/020517
Kind Code:
A1
Abstract:
A thermoplastic elastomer excellent in rubber elasticity and extrudability and a molded object thereof. The thermoplastic elastomer comprises a partly or wholly crosslinked rubber (A), an isotactic polypropylene (B) having an isotactic pentad content of 0.8 or higher, a syndiotactic polypropylene (C) having a syndiotactic pentad content of 0.6 or higher, and a softener (D), the content of the syndiotactic polypropylene (C) being in the range of 0.5 to 10 wt.% based on the sum of the crosslinked rubber (A), isotactic polypropylene (B), syndiotactic polypropylene (C), and softener (D), the thermoplastic elastomer having a melt flow rate of 0.01 to 1,000 g/10 min as measured in accordance with ASTM D1238 at 230°C under a load of 10 kg. The molded object is obtained by extrusion-molding the elastomer.
