Abstract
The results of mechanical testing of compacted ultra-high-molecular-weight PE reactor powder in air and in adsorption-active liquid environments, which dramatically reduce the interfacial surface energy, were analyzed. The intergranular character of brittle fracture of the samples in air and in decane made it possible to assess the contribution from cohesive intergranular bonds to the overall strength (∼75%). It was shown that the formation of intergranular bonds depends on the intensity of molecular mobility in the polymer. The strength of the compacted material was found to be determined to a great extent by the deformation of the boundary layers in contacting grains. The formation of the intergranular layers can be accompanied by such a deep structural rearrangement in the nascent material that the structure of the intergranular layers upon the compaction of various reactor powders with different physical-and-mechanical characteristics becomes approximately the same.
