Most of the Langmuir films we have discussed are made up of charged amphiphiles such as the fatty acids in Chapter IV and the lipids in Sections XV-4 and 5. Depending on the pH and ionic strength of the subphase, electrostatic effects can become quite important. Here we develop the theoretical foundation for charged films with the Donnan relationship. Then we mention the influence of subphase pH on film behavior. 

Nevertheless, each of the more popular isotherm models have been found useful for modeling adsorption behavior in particular circumstances. The following outlines many of the isotherm models presently available. Detailed discussions of derivations, assumptions, strengths, and weaknesses of these and other isotherm models are given in references 4 and 7—16. 

Strengths and moduli of most polymers increase as the temperature decreases (155). This behavior of the polymer phase carried over into the properties of polymer foams and similar dependence of the compressive modulus of polyurethane foams on temperature has been shown (151). 

For both geometries the diffraction efficiency approaches unity in value for Atransmission hologram exhibiting a periodic behavior (24,25) efficiency as a function of the grating strength ( ), whereas the reflection efficiency exponentially approaches unity. 

EPDM-Derived Ionomers. Another type of ionomer containing sulfonate, as opposed to carboxyl anions, has been obtained by sulfonating ethylene—propjlene—diene (EPDM) mbbers (59,60). Due to the strength of the cross-link, these polymers are not inherently melt-processible, but the addition of other metal salts such as zinc stearate introduces thermoplastic behavior (61,62). These interesting polymers are classified as thermoplastic elastomers (see ELASTOLffiRS,SYNTHETIC-THERMOPLASTICELASTOLffiRS). 

Technical Magnetic Behavior. When a magnetic-field strength H is appHed to a ferromagnetic or ferrimagnetic material, the latter develops a flux density or iaduction as a result of orientation of the magnetic domains. The relation between B and H is... 

Film. Blown film manufactured from PB has a high tensile strength and exhibits good resistance to tear, impact, and puncture (47). Such film also exhibits hard-elastic behavior that is, it can recover its original length even after extensive stretching. Some properties of PB film are given in Table 5.
