New Concepts in Polymer Science
Yu. A. Mikheev and G.E. Zaikov
This monograph is intended for elucidation of the novel trend inchemical physics regarding the polymer non-crystalline phase. Itstresses the physical phenomena affecting the kinetics and mechanism ofchemical 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 polymericchains, which co-operate as a molecular-chain sponge.
The NCPM model presented is proved for adequate description of principalstructure-physical phenomena to elaborate the scheme ofstructural-kinetic modeling of chemical reactions in bulky polymers.Structure-physical phenomena elucidated in the monograph are:
-- peculiarities of polymer plasticization and polymer blending withliquids;
-- structural and thermodynamic aspects of sorption of low molecularspecies;
-- properties of ESR (spin) probes and optical (molecular) probes;
-- features of water absorbed by polymers;
-- mechanical and thermal effects generated by the molecular-chainsponge;
-- supramolecular aspects of NCPM chemical physics.
This monograph includes the structural-kinetic modeling of complexpolymer chemical reactions. It deals with the problem of mechanism andkinetics of free radical chain reactions using thermal and photochemicalmodel 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), andisotactic polypropylene. In all cases, the supramolecular heterophasemechanism of the processes, which was unknown for homogeneous systems,was proved. Furthermore, heterophase mechanisms of photochemicalreaction between naphthalene and cellulose triacetate and photolysis ofpoly(methyl methacrylate) proceeding as a photochain reaction areindicated.
This monograph is of value and interest to students, postgraduates andscientists searching for new properties of polymers for appliedpurposes.
