- Аннотация: Rheological explosion in polymers under uniaxial compression in an open volume occurs at the end of continuous rapid plasticdeformation after several stages of creep. Two types of polymers were chosen for this study: brittle glassy amorphous polystyrene andthermoplastic 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 rheologicalexplosion. The pores appear in polymer in this process, and their shape and size distribution were derived from X-ray experiments. The mainreason for the formation of pores in polymer samples in rheological explosion experiments is the intense microshifts in the polymer volumeunder the action of high applied pressure.
