简介：在我们的当前的工作，在有起核心作用的代理人的isotactic聚丙烯(iPP)的水晶的生长上的shear温度的效果被调查借助于在situ二维的宽角度的X光检查衍射(2D-WAXD)。在低砍温度，面向的先锋是的形成的砍导致难由于分子的链的弱活动性放松回到随机的卷的状态。因此，很多的面向的晶体被砍导致导致面向的先锋，当水晶极大地被压抑时。作为shear温度增加，面向的水晶逐渐地与水晶的减少一起增加。这被推出水晶的内容在增加到的shear温度(最大值)在静止结晶化发现的价值在结晶化动力学上的流动的加速的效果哪个完全被擦掉几乎与那一样。我们的工作在结构和iPP的性质操作在调整水晶并且这样表明它的意义。
