The rheological properties of molten mixtures of polyoxymethylene and copolyamide have been investigated by the methods of capillary viscometry over a wide range of shear stresses. It has been found that at relatively close values of the melt viscosi

Having relatively similar melt viscosities, polyoxymethylene (POM), and copolyamide (CPA) on mixing (over the entire range of composition) form mixtures which differ from the initial polymers in viscosity and elastic properties of melts. The type of

The phenomenon of specific fibrillation from melts of polymer mixtures is considered (using mixtures of polyoxymethylene with copolyamide as an example) when, in contrast to conventional fibre spinning methods, a complex thread consisting of hundreds

The current state of research on the plastic properties of compositions based on reactive oligomers is assessed. Methods used to study their properties during deformation are examined. The influence of external factors, composition, and specific stru

The variation in molecular weight and in the rheological properties of low density PE during flow of the molten polymer in capillary and rotational viscometers, has been studied. It is shown that at high rates of shear and temperatures of 240–270°

In the prestationary deformation regime relaxation times decrease both before and after passage through the ultimate shear strength, i. e., independent of whether the stresses at which relaxation began were growing or decreasing. The relaxation prope

The unsteady flow effect has been studied experimentally in cylindrical capillaries for polypropylene melts with melt indices differing over an approximately 30-fold range. The entrance losses were negligibly small. The flow curves obtained on capill
