Study of the change in morphological structure of UHM yarns on storage by the polarization interferometry method

Autor: A. S. Andreev, V. I. Kucher, O. S. Karchmarchik, I. K. Nekrasov

Publikováno v: Fibre Chemistry. 21:335-336

Dependences of birefringence of the radial coordinate have been obtained for “old” and relatively fresh UHM yarns using the polarizing interference microscope. Storage of UHM yarns in air leads to increased strength and elongation at break in mic

The Sedimentation of Polydisperse Polymers

Autor: I K Nekrasov

Publikováno v: Russian Chemical Reviews. 48:699-713

The most important problems in the sedimentation of one component of two-component mixtures and polydisperse polymers have been discussed. Particular attention has been paid to the application of theory in the treatment of sedimentation data. It has

The method of synthesis as a factor in the structure of the polymer solutions and in the properties of fibre spun from poly-m-phenylene isophthalamide

Autor: V. I. Klenin, E. A. Vorob'ev, I. K. Nekrasov, L. V. Prozorov, T. V. Martynova, B. I. Zhisdyuk

Publikováno v: Fibre Chemistry. 7:106-107

There are two known methods /I/ of synthesizing poly-m-phenylene isophthalamide (PmPIPA), viz. by emulsion polycondensatien and by low-temperature polycondensation in a solution. The latter can be conducted in one or two stages. In the work reported
