Document Type and Number:
WIPO Patent Application WO/2007/102227
Kind Code:
A1
Abstract:
Disclosed are a block copolymer having different segments bound to one another and showing various useful physical properties and a process for producing the block copolymer with good efficiency. An olefin block copolymer comprising (i) a polymer block which is produced from at least one olefin selected from olefins having 2 to 20 carbon atoms and (ii) a polymer block which is produced from at least one olefin selected from olefins having 2 to 20 carbon atoms and is different from the polymer block (i), any adjacent polymer blocks being different from each other, the olefin block copolymer having an Mn (number average molecular weight) of 500 or higher and a Mw/Mn value (molecular weight distribution) of 1.5 or lower.
