Thermomechanical, rheological and X-ray methods have been used to study a series of poly(decamethyleneterephthaloyl-bis-4-hydroxybenzoates) in the interval M = (0.8−4.2) × 104. The LC melts of the polymers constitute quasiviscoplastic liquids. The

The specific features of the rheological properties of lyotropic liquid crystal systems are demonstrated, using aqueous solutions of propoxycellulose as an example. These properties include the existence of maxima on the plots of viscosity, elastic s

The authors discuss the relaxation of the first difference of the normal stresses σ(t) after cessation of steady shear flow in viscoelastic polymer systems in the linear region of their mechanical behavior. They show that this phenomenon is associat

The effects of the MWD on the highly elastic properties of elastomers were examined during flow under shear stress. The high elasticity modulus was found to be independent (in the case of polybutadiene as example) of the mol. wt., when the elastomers

An investigation has been carried out into the effect of the fractional composition on the rheological (flow and elastic) properties of a system, using mixtures of polybutadienes with narrow molecularweight distribution (MWD). For mixtures of high-mo

The poly(butyl methacrylate) studied is a polymer with a normal molecular weight distribution and a relatively low molecular weight close to Mc, the critical molecular weight from the viscosity–molecular weight relation. The polymer was subjected t

A study of the variation in viscosity of polymers plasticized with oligomer and low molecular weight substances revealed the existence of three ranges of molecular weight ratio of components of systems, in which plasticization has a varying effect. O

The viscous properties of SBS block copolymers (of “Cariflex TR-1102” in this work) have been determined with the rate of shear being varied by 108 times. It has been shown that in the region of low shear rates the polymer behaves as a structured
