Title:
THERMOPLASTIC ELASTOMER MOLDING
Document Type and Number:
WIPO Patent Application WO/2004/011551
Kind Code:
A1
Abstract:
A molding of thermoplastic elastomer composition that while exhibiting low hardness, is excellent in compression set and has satisfactory tensile strength. In particular, a molding of thermoplastic elastomer composition comprising (a) 55 to 95 wt.% of aromatic vinyl-isoprene block copolymer having two or more polyaromatic vinyl blocks of 14,000 to 100,000 weight average molecular weight, (b) 0 to 40 wt.% of aromatic vinyl-isoprene diblock copolymer and (c) 5 to 33 wt.% of polyisoprene of 5000 to 300,000 weight average molecular weight, wherein the content of aromatic vinyl monomer units is in the range of 14 to 30 wt.% based on the total weight of components (a), (b) and (c). This molding can be widely employed in various uses where the characteristics thereof are useful, such as roll members, e.g., form advance roll and paper feed roll of OA equipment and office machines.
