Stabilization and regulation of the rheological properties of electroconducting solutions of polyvinyl alcohol

Autor: N.K. Kireyeva, Yu.D. Semchikova, D.N. Yemel'yanov

Publikováno v: Polymer Science U.S.S.R.. 26:2523-2529

The patterns of ageing of the electroconducting PVA-water-NaCl system containing no more than 15% polymer have been studied. The existence of two regions of the concentration of PVA responsible for the different rheological behaviour of the solutions

Publikováno v: Polymer Science U.S.S.R.. 31:1534-1541

Change in viscosity on exposure to shear deformation and temperature in the region of phase separation is examined for concentrated PS and PMMA solutions. Below the temperature of phase separation depending on the shear rate the viscosity of the syst

Publikováno v: Polymer Science U.S.S.R.. 17:1536-1540

The rheological properties of concentrated solutions of “comb-like” polyalkylmethacrylates (PMA) were investigated in their hydrated monomers. It is shown that solutions of PMA with up to six carbon atoms in side ester groups have viscous flow an
