From Polyacrylonitrile, Its Solutions, and Filaments to Carbon Fibers: I. Phase State and Rheology of Basic Polymers and Their Solutions
Valery G. Kulichikhin,Valery G. Kulichikhin,Sergey O. Ilyin,M. V. Mironova,A. K. Berkovich,Ilya E. Nifant'ev,A. Ya. Malkin +6 more
TL;DR: In this article, the phase state and rheological properties of PAN-DMSO solutions were studied and it was shown that small additions of non-solvent (water) enhance viscoelasticity of the solution, whereas a large amount of water results in gel formation; beyond a certain threshold of water concentration, macroscopic phase separation takes place.

The exothermal effects of superimposed processes of activated anionic polymerization of ε-caprolactam and crystallization of the polymer formed
TL;DR: In this article, a calorimetric investigation of the anionic polymerization of e-caprolactam and of the crystallization of the polymer produced was carried out under isothermal conditions with the use of activators of various chemical types and functionality.

Surface instabilities
A. Ya. Malkin
- 01 Dec 2008
TL;DR: In this paper, a comprehensive review of the physical properties of convective instabilities at the interface of a free surface is presented. But the authors focused on the effect of the elasticity of a flowing liquid, which is inherent to polymer solutions and melts, on the character of interaction between the liquid and the solid wall.

Comparative description of the peculiarities of deformation of polymer and plastic disperse systems
G. V. Vinogradov,A. Ya. Malkin +1 more
TL;DR: In this article, various conditions of deformation of polymer melts are studied on a rotational elastoviscometer at different constant speeds of rotation of one of the measuring surfaces, and it is shown that raising the speed causes periodic slippage along the solid surface, ending in a rupture in the melt or complete tearoff of the deforming melt from the wall.
