摘要：

Structural studies were carried out and physicomechanical characteristics of samples of ultrahigh molecular weight polyethylene (UHMWPE) were determined for successive stages (compacting/monolithization-orientational stretching) of the continuous solid-state processing of nascent reactor powders of UHMWPE (RP UHMWPE) into high-strength tapes. The use of nascent RP UHMWPE with the morphology, molecular weight, and bulk density optimal for solid-state processing makes it possible to obtain high-strength (similar to 3 GPa) and high-modulus (120-130 GPa) tapes. The conditions for both compacting/monolithization and the orientational stretching have a significant effect on the structure and properties of highly oriented tapes and can be optimized in order to prepare materials with a complex of the highest elastic-strength characteristics.
