The final objective of this study is to maximize functions and performances of natural rubber (NR) which is a very important biomass for industrial uses such as pneumatic tires.For this purpose, strain-induced crystallization of NR samples from different clones are studied using a dynamic condition at a synchrotron radiation beam line i.e. simultaneous measurements of wide-angle X-ray diffraction and tensile-mode deformation. The results are to be of use for the selection of better NR : Strain-induced crystallization has been assumed to be the most important factor to determine superior mechanical properties of NR. Effects of micron-size dirt, non-rubber components such as aliphatic acid and proteins contained in NR, and nano-fillers such as carbon black on the behavior in strain-induced crystallization of NR were elucidated.A few different clones of Hevea have been obtained from Sri Lank and Thailand. Using these samples, the main experiments to elucidate the effect of Hevea clones on the crystallization are now in progress and will be reported in a near future.

本研究的最终目标是最大限度地发挥天然橡胶（NR）的功能和性能，天然橡胶是一种非常重要的工业用生物质，如充气轮胎。为此，利用同步辐射束流线的动态条件，即同时测量广角x射线衍射和拉伸模变形，研究了来自不同克隆的NR样品的应变诱导结晶。研究结果为选择更好的NR提供了参考依据：应变诱导结晶被认为是决定NR优异力学性能的最重要因素。研究了微米级污垢、NR中所含的非橡胶成分如脂肪酸和蛋白质以及纳米填料如炭黑对NR应变诱导结晶行为的影响。已经从斯里兰卡和泰国获得了几种不同的橡胶树克隆。利用这些样品，阐明橡胶树克隆对结晶影响的主要实验正在进行中，并将在不久的将来报道。
