摘要：

应用小角X射线散射技术研究了聚丙烯的长周期,结果表明,聚丙烯的相关函数长周期与它的Bragg长周期不相等;应用小角散射理论和结晶聚合物的三相结构模型研究了聚丙烯的2种长周期不同的原因,得到结论,聚丙烯的Bragg长周期接近于它的相关函数长周期与结晶过渡层的厚度之和.这个结论与小角散射实验的结果一致.

Abstract:

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.

Key words: small-angle X-ray scattering, polypropylene, three-phase structure, correlation function
