Concept of Micellar-Spongy Nanophases in Chemical Physics of Polymers

The monograph is intended for elucidation of the novel trend in chemical physics regarding the polymer non-crystalline phase. It stresses the physical phenomena affecting the kinetics and mechanism of chemical reactions proceeding in the non-crystalline polymer matrix (NCPM). NCPM is depicted in terms of a supramolecular (carcass-micellar) model. The model is thought to reflect heterophase packing of polymeric chains, which co-operate as a molecular-chain sponge.The NCPM model presented is proved for adequate description of principal structure-physical phenomena to elaborate the scheme of structural-kinetic modeling of chemical reactions in bulky polymers. Structure-physical phenomena elucidated in the monograph are: -peculiarities of polymer plasticization and polymer blending with liquids; -structural and thermodynamic aspects of sorption of low molecular species; -properties of ESR (spin) probes and optical (molecular) probes; -features of water absorbed by polymers; -mechanical a thermal effects generated by the molecular-chain sponge; -supramolecular aspects of NCPM chemical physics.This monograph includes the structural-kinetic modeling of complex polymer chemical reactions. It deals with the problem of mechanism and kinetics of free radical chain reactions using thermal and photochemical model reactions of dibenzoyl peroxide with glassy-like polymers (cellulose triacetate, polycarbonate, polystyrene, polyamide PA-548), viscoelastic polymers (atactic polypropylene, polyamide PA-548, polyethylene, polyisobutylene, melted poly(ethylene oxide), and isotactic polypropylene. In all cases, the supramolecular heterophase mechanism of the processes, which wasunknown for homogeneous systems, was proved. Furthermore, heterophase mechanisms ofMikheev, Yu A. is the author of 'Concept of Micellar-Spongy Nanophases in Chemical Physics of Polymers', published 2004 under ISBN 9789067644020 and ISBN 9067644021.
