The Concept of Micellar-Sponge Nanophases in Chemical Physics of Polymers
ISBN: 9789067644020 / Angielski / Twarda / 2004 / 450 str. Termin realizacji zamówienia: ok. 22 dni roboczych (Bez gwarancji dostawy przed świętami) 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... The monograph is intended for elucidation of the novel trend in chemical physics regarding the polymer non-crystalline phase. It stresses the physical...

Structure of the Polymer Amorphous State
ISBN: 9789067644013 / Angielski / Twarda / 2004 / 484 str. Termin realizacji zamówienia: ok. 22 dni roboczych (Bez gwarancji dostawy przed świętami) The basic problem of polymer physics is obtaining a structure-propertiesa 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...

ISBN: 9789067644068 / Angielski / Twarda / 2004 / 319 str. Termin realizacji zamówienia: ok. 22 dni roboczych (Bez gwarancji dostawy przed świętami) The behavior of substances in solutions may not be adequately characterized by the effect of any single physicochemical parameter of solvents, nor are numerous semi-empirical scales of the solvent effect (their a polaritya ) suitable for their limited selections only. In recent decades, it has been found that the variation of reaction rate constants in solutions or that spectral parameters of dissolved substances are determined by the total effect of different solvation processes. This monograph presents numerous examples of such an approach and characterizes various empirical and...
