Abstract The present invention relates to a montmorillonite nanometer composite polyolefine material, and is characterized by that the flake layer portion of montmorillonite or completely-decomposed montmorillonite can be uniformly dispersed in the polyolefine, the weight ratio of montmorillonite and polyolefine is 1:4-1:99, the montmorillonite adopted by this invention is H-montmorillonite, Na-montmorillonite, Mg-montmorillonite or Ca-montmorillonite, and the polyolefine is polyethylene, polypropylene or polystyrene. Its synthesis method is simple, and is favorable for industrial production, can be used for stereo-oriented polymerization of alpha-olefine, and in the obtained montmorillonite nanometer composite polyolefine material, the polyolefine possesses high degree of stereoorientation.
