Title:
OLEFIN BLOCK COPOLYMER AND SHEET-SHAPED MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2012/099415
Kind Code:
A2
Abstract:
The present invention relates to an olefin block copolymer which exhibits superior elasticity and heat resistance, and which therefore may be desirable for use in forming an anti-slip pad. The present invention also relates to a sheet-shaped molded body comprising the copolymer. The olefin block copolymer comprises a plurality of blocks or segments containing an ethylene-based or propylene-based repeating unit and an α-olefin-based repeating unit, wherein the two units have different weight fractions. A predetermined relationship is satisfied when a 5 to 10 kg weight is applied to the sheet-shaped molded body of the block copolymer for 12 hours or longer at a temperature of 60°C or higher, and the weight is then removed.
