SOLUTION: The first part contains a crosslinked product of a polymer in which a crosslinkable compound is grafted on a first polyolefin having a weight average molecular weight (Mw) of 1,000 to 50,000 g / mol; and a weight average molecular weight (Mw). ) Is 200,000 to 1,000,000 g / mol, the second part containing the second polyolefin; and a method for producing the same. [Effect] The mechanical properties and heat resistance of the separator can be improved in a balanced manner, the problem that the manufacturing cost increases due to the elution and disposal of the crosslinkable compound can be solved, and the productivity and economy can be maximized. Can be done. [Selection diagram] None |
