“…If (a + a/e a ) 5 1, there are no uncross-linked polystyrene units and formula (22) goes over into relationship (20). The dependence of T g on a obtained using Eqns ( 22) and ( 20) is shown in Fig.…”

“…The temperature of freeing the mobility of the structural elements of native and fully cured polymers decreases as the temperature of isothermal curing increases. A model of largescale motion in highly cross-linked polymer networks was pro- posed, 20 which allowed one to rationalise the experimental results obtained in a pulse NMR study of epoxy networks. Physical methods for the analysis of the structure of highly cross-linked networks are most widely used.…”

“…Finally, one should keep in mind that the model network considered here has a simple topology (chains linked by tri-or tetrafunctional cross-link points), whereas the real network contains `tales', small rings, a sol fraction and other defects responsible for considerable uncertainty of the relaxation time spectra of a polymer. 95,103,104…”

The known methods for the assessment of the molecular The known methods for the assessment of the molecular mass distribution of bulk polymers are considered. These are mass distribution of bulk polymers are considered. These are based on the analysis of the melt flow curves, the frequency based on the analysis of the melt flow curves, the frequency dependence of the relaxation modulus, the shape of the free dependence of the relaxation modulus, the shape of the free induction decay curve (pulse nuclear magnetic resonance spectro-induction decay curve (pulse nuclear magnetic resonance spectroscopy) and the temperature dependence of compliance in the scopy) and the temperature dependence of compliance in the region of the rubbery elasticity plateau (thermomechanical anal-region of the rubbery elasticity plateau (thermomechanical analysis). The bibliography includes 121 references. ysis). The bibliography includes 121 references.
