Rheological explosion in polymers under uniaxial compression in an open volume occurs at the end of continuous rapid plastic deformation after several stages of creep. Two types of polymers were chosen for this study: brittle glassy amorphous polystyrene and thermoplastic semi-crystalline polypropylene. Electric pulses were detected during explosion, and their spectra were analyzed with two models. X-ray diffraction methods were used to investigate changes in the structure and morphology of polymers during deformation and rheological explosion. The pores appear in polymer in this process, and their shape and size distribution were derived from X-ray experiments. The main reason for the formation of pores in polymer samples in rheological explosion experiments is the intense microshifts in the polymer volume under the action of high applied pressure.

在开放空间中，在单轴压缩下，聚合物的流变爆炸发生在蠕变几个阶段后，连续快速塑性变形结束时。本研究选择了两种类型的聚合物：脆性玻璃态无定形聚苯乙烯和热塑性半结晶聚丙烯。在爆炸过程中检测到电脉冲，并使用两种模型分析其频谱。X射线衍射方法用于研究聚合物在变形和流变爆炸过程中的结构和形态变化。在此过程中，孔出现在聚合物中，其形状和尺寸分布是根据X射线实验得出的。
