The cation exchange stratified filling up material of 1 where it is selected from the group which consists of the cation exchange stratified chemical compound other than the cation exchange stratified inorganic silicate and the silicate types being processed acid at least, the nano- composite formation method of being due to the olefin polymerization which the catalyst which is activated for the olefin polymerization to the occasion where it contacted with the bulking agent where the stratified structure was destroyed, said acid was processed is mixed. Olefin, when (a) also the alkyl aluminum under non- existing of the catalyst or (b) the activated possible catalyst is poly- alkyl metal chemical compound, also the alkyl aluminum under existing of the catalyst, the description above contacts with the catalyst/bulking agent blend which is activated, the polyolefine and acid forms the nano- composite which includes the bulking agent which was processed. With feature of specification, high fill nano- composite master batch is manufactured making use of the bulking agent of ten kind of quantity which the nano- composite forms 30 weight % at least. Next, the aforementioned master batch blending or more the olefin polymer of 1 types or 2 types at the specified quantity, it is possible to obtain the nano- composite which possesses the fill of desire. The bulking agent is the clay desirably, you can list the montmorillonite as the example. The catalyst is the non metallocene catalyst desirably, it is the nickel complex which is most desirable, possesses the iminokarubokisamidato ligand.
