The possibility of reducing the duration of synthesis of poly(p-phenylenebenzobisthiazole) (PPBT) from 2,5-diamino-1,4-dimercaprobenzene and terephthalic acid in polyphosphoric acid medium with production of a high-molecular-weight with [η] = 24-29

Autor: V. I. Ognev, V. N. Odnoralova, V. A. Platonov, V. N. Kiya-Oglu, G. A. Budnitskii

Publikováno v: Fibre Chemistry. 32:26-32

The effect of the intrinsic viscosity and concentration of polymer in LC solution on the mechanical properties of PPBT yarn was demonstrated. In examining the spinning stability of PPBT yarns, use of spinnerets with an opening diameter of 0.25 mm and

Effect of the die hole diameter and air space temperature on the stability of formation of fibers from poly(p-phenyleneterephthalamide) solution

It was shown that the region of resonance in drawing of a jet of poly(p-phenyleneterephthalamide) solution is shifted toward low values of the air spaces when a die with the corresponding hole diameter is used. In drawing of thin jets in resonance co

Effect of spinning conditions on the stationary regime region in stretching a jet of a solution of poly-p-phenyleneterephthalamide in an air gap

Autor: G. I. Kudryavtsev, V. I. Ognev, V. N. Kiya-Oglu

Publikováno v: Fibre Chemistry. 25:86-89

The spinning of a yarn from sulfuric acid solutions of poly-p-phenyleneterephthalamide through an air gap in the region of high stretch ratios is unstable because of the onset of pulsations in jet diameter, which is known for polymer melts as stretch

Hydrodynamic forces acting on a cylinder set in motion abruptly

Autor: M. G. Shcheglova, V. I. Ognev

Publikováno v: Fluid Dynamics. 18:468-472

An attempt has been made to measure directly the forces (drag and lift) that act on a cylinder under the conditions of a fairly complicated unsteady motion in which the velocity is acquired almost instantaneously from the state of rest.
