Supplemental Thermodynamics

These supplemental thermodynamics are provided to support the performance trends developed in Sections 2.1.2 and 2.1.3. The descriptions are not intended to be a detailed explanation.

These deductions from basic facts of observation interpreted according to the rigorous laws of thermodynamics do not alone offer an insight into the structural mechanism of rubber elasticity. Supplemented by cautious exercise of intuition in regard to the molecular nature of rubberlike materials, however, they provide a sound basis from which to proceed toward the elucidation of the elasticity mechanism. The gap between the cold logic of thermodynamics applied to the thermoelastic behavior of rubber and the implications of its...

As pointed out in the foregoing, there are two specific peculiarities qualitatively distinguishing these systems from the classical ones. These peculiarities are intramolecular chemical inhomogeneity of polymer chains and the dependence of the composition of macromolecules X on their length l. Experimental data for several nonclassical systems indicate that at a fixed monomer mixture composition x° and temperature such dependence of X on l is of universal character for any concentration of initiator and chain transfer agent [63,72,76]. This function X(l), within the context of the theory proposed here, is obtainable from the solution of kinetic equations (Eq. 62), supplemented by thermodynamic equations (Eq. 63). For heavily swollen globules, when vector-function F(X) can be presented in explicit analytical form... 

For the case of interest, copolymerization dynamics is described by nonlinear equations (Eq. 62) where variable plays the role of time, supplemented by the thermodynamic relationship (Eq. 63). The instantaneous state of the system characterized by vector X may be represented by a point inside the unit interval X + X2 = 1. The evolution of composition X in the course of... 

Fluorine thermochemistry itself has not been previously reviewed, but has tended to be included in more general reviews and reports, or in data compilations (141,123,151). The most comprehensive literature survey, covering the years 1949-1961 (9), supplements the N.B.S Circular and Notes (203). (N.B.S. Technical Notes 270-3 to 270-7 issued from 1969-1973 were unfortunately published without literature references.) Subsequent work was conveniently traced from annual issues of the Bulletin of Chemical Thermodynamics, and from 1977 to 1979 (May) by accessing the Chemical Abstracts data files. Experimental aspects of fluorine thermochemistry are included in two rather dated volumes (214), and only general detail will be given in this review.

The first edition of this puhhcation dates from 1973 (I. Barin, O. Knackle. Thermodynamic Properties of Inorganic Substances. Springer-Verlag Berlin, 1973). A supplement, coauthored hy O. Kuhaschewski, was released in 1977.
