Dynamic moduli of fumed silica suspensions in aqueous solutions of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers and PEO homopolymers were measured as a function of surface coverage. Since the block copolymers and PEO are adsorbed on the silica surfac

The rheological properties of three cellulose samples are investigated, including the dependence of the non-Newtonian Index, structural viscosity and zero shear viscosity on temperature and the concentration of their paraformaldehyde/dimethyl sulfoxide solutions; the values of viscous flow activatio
## Abstract Paper sheets prepared from bleached bagasse and paper grade wood pulp were impregnated in a carboxymethyl cellulose solution. After drying the prepared samples were cured at 100Β°C or 140Β°C. The measured improvement of the mechanical properties of the treated samples depends on time and
