Abstract
Aspects of a gel technology for obtaining polyvinyl alcohol fibers from the high-molecular-weight polymer are examined, and studies are made of the rheological and morphological characteristics of fibers formed from solutions of different concentrations. It is shown that the use of a dry-wet forming method instead of the competing methods of thermotropic transformation and wet precipitation makes it possible to obtain fibers having a strength of 2.2 GPa and an elastic modulus of up to 32 GPa.
