The basic problem of polymer physics is obtaining â ~structure-propertiesâ (TM) correlations for their future application for practical purposes. However, these cannot be obtained without the development of a quantitative model of the polymer structure. This problem has been actively investigated during the last 45 years, which resulted in obtaining a great amount of experimental (mostly indirect) proofs of existence of the local order in the polymer amorphous state. Now, the time has come for creating a structural model of polymer basing based on the local order ideas. The cluster model, as presented in this monograph, of the polymer amorphous state structure represents the realization of such attempts. The development of this cluster model is based on well-known experimental observation: the behavior of glassy polymers in the area of stimulated high-elasticity plateau is described in the framework of rubber elasticity concepts. This gives an opportunity to present the local order (cluster) zone as a multifunctional entanglement of the physical network consisting of several collinear closely packed segments of different macromolecules (the amorphous analogue of crystallite with extended chains) and surrounded by a packless matrix. An independent method for assessing local order zone fraction in the structure has been elaborated. Segment length in the cluster equals the length of the chain statistical segment that gives a correlation between molecular and structural parameters of the polymer. Application of the cluster model allowed description and obtaining of analytical â ~structure-propertiesâ (TM) correlations for many processes proceeding in polymers: elasticity, yielding, degradation, transport, some thermodynamic processes, structural relaxation, plasticization, structural stabilization at thermo-oxidative degradation, etc. The relation between the cluster model and some modern physical concepts, for instance fractal analysis, fluctuation free volume kinetic

This book gives a fresh point of view on the curing processes, structure and properties of crosslinked polymers. The general view is that the structure and properties of crosslinked polymers are defined by their density, this book demonstrates that the parameters are defined by the supermolecular (a more precisely, supersegmental
