More Information
Summary:Provided is a block polymer (X) containing, as structural units, a polyolefin structure derived from a polyolefin (A) below and a polyolefin structure derived from a polyolefin (B) below. The polyolefin (A) contains a C3-C8 α-olefin as a structural monomer with α-olefin portions having an isotacticity of 70 to 100%, has a number average molecular weight of 1000 to 200000, and has a carbon-carbon double bond number of 0.01 to 8.0 per 1000 carbon atoms. The polyolefin (B) contains a C3-C8 α-olefin as a structural monomer with α-olefin portions having an isotacticity of 1 to 65%, and has a number average molecular weight of 1000 to 200000.
