Effect of the reaction between cellulose hydrate and water vapour on the properties of its hydrogels

Autor: N.A. Vengerova, B. S. Él'tsefon, A. R. Rudman, V.B. Yeremeyev

Publikováno v: Polymer Science U.S.S.R.. 29:2378-2384

The problem of the interaction between cellulose hydrate and water in the vapour and in the liquid phase is considered with cellulose-hydrate membranes with an open structure being taken as an example. Under conditions of enhanced humidity, it has be

Conditions of formation and properties of membranes of polyelectrolyte complexes prepared using weak polyelectrolytes

Autor: A.B. Zesin, B. S. Él'tsefon, A. R. Rudman, N.A. Vengerova, R.I. Kalyuzhnaya, Ye.F. Razvodovskii

Publikováno v: Polymer Science U.S.S.R.. 17:3201-3209

A method is proposed for obtaining semi-permeable membranes swelling in water from solutions of weak polyelectrolyte complexes. Volatile, weak low molecular weight acids and bases were selected as solvents. Membrane formation depends to a large exten

Comparative evaluation of cuprophane and cellophane used as membranes for hemodialysis

Autor: N. A. Vengerova, A. R. Rudman, B. S. Él'tsefon

Publikováno v: Biomedical Engineering. 10:224-228

Investigations into the structure, mechanical properties and permeability of the Soviet-made cellophane, cellulose film No 100 and cuprophane have shown the Soviet-made cellophane membrane to be inferior to cuprophane with regard to the strength and
