In the paper, small angle X-ray scattering technique was used to study long periods of polypropylene.The results indicate that the correlation function long period of polypropylene and its Bragg long period are not identical. We applied the theory of small-angle scattering and three-phase model of crystalline polymer to study the reason of differences of two kinds of long periods of polypropylene and draw a conclusion that the Bragg long period approaches the correlation function long period plus the thickness of the transition layer. The conclusion is consistentwith our small-angle scattering experimental results.
