The effect on the dynamics of ripening of viscose in the presence of carbonyl-containing compounds: hexamethylenetetramine (urotropin), sodium sulfoxylate (Rongalite C), and dimethylolurea, was investigated. A hypothesis was advanced concerning the p

High-molecular-weight copolyesters based on ethylene glycol, tetraphthalic and 4,4′-biphenyl dicarboxylic acids containing up to 10.3 mole % of a second component were synthesized in the presence of homo- and heterogeneous catalysts. It was found t

The viscosity properties of melts of fibre-forming polypropylene (PP) and poly(butylene terephthalate) blends were investigated in the entire range of ratios at different stresses and shear rate gradients at 230–250°C. It was shown that melts of f

The possibility of synthesizing poly(AN-co-VA-co-AMPS) fibre-forming copolymer in a 51.5% aqueous solution of sodium thiocyanate is demonstrated. Slowing of the rate of polymerization occurs when MAA is replaced by its isomeric analog VA as a result

Sixty years of experience in manufacture of fibres from acrylonitrile polymers and copolymers suggest favorable prospects for the development of this kind of textile stock. The characteristics of the primary and supermolecular structure of this class

We propose a new mechanism for far-infrared (FIR) stimulated emission in quantum dot structures with gain and emission frequency modulated by acoustic phonon scattering. This novel mechanism is based on carrier injection into coupled quantum dot stru
