Gelatinization Coefficient of Nitrocellulo es and Coefficient de plasticitd. In the paper entitled "Plasticites des psites de Poudre B , the term "coefficient de plasdeite is defined and a simple apparatus for its determination is described Ref Anon, MP 19, 146-53(1922)... 

Coefficient de gelotlnisation or Pouvoir gelo tinisant(Fr) (Gelatinization Coefficient or Gelling Power). In order to determine the amts of various substances required to cause gelatinization of lOOg of NC, the foilowing tests were developed in France ... 

This stipulation of the interaction parameter to be equal to 0.5 at the theta temperature is found to hold with values of Xh and Xs equal to 0.5 - x < 2.7 x lO-s, and this value tends to decrease with increasing temperature. The values of = 308.6 K were found from the temperature dependence of the interaction parameter for gelatin B. Naturally, determination of the correct theta temperature of a chosen polymer/solvent system has a great physic-chemical importance for polymer solutions thermodynamically. It is quite well known that the second viiial coefficient can also be evaluated from osmometry and light scattering measurements which consequently exhibits temperature dependence, finally yielding the theta temperature for the system under study. However, the evaluation of second virial...

An enzyme is immobilized uniformly in a gelatin slab (thickness L and area A). One side is in contact with substrate solution (Csb) and the other side is in contact with a glass plate. The mass transfer coefficient bn the surface of the gelatin is ks. 

Composite Propellants. These are nonhomo geneous mixts of a finely ground oxidizer (such as Amm perchlorate or nitrate) in a matrix of plastic, resinous or elastometric material (Ref 24, ppl0-ll 34-40). As these proplnts are not based on colloided NC, they are not considered as "Colloidal Propellants", but are described separately as "Composite Explosives (See also Coefficient de gelatin sation and Coefficient de gonflement)... 

On a molecular scale there is no sharp boundary between hydrodynamically stagnant and movable solvent molecules. As discussed In sec. 2.2, the, say tangential, diffusion coefficient of water near many surfaces may be somewhat lower than in bulk, but it is not zero. The very existence of ionic conduction In the layer(s) adjacent to surfaces also points to non-zero mobility. Yet, phenomenologically such layers behave as immobilized. This looks like a paradox, but the phenomenon is encountered in other places as well. For Instance, a few percent of gelatin added to water may hydrodynamically immobilize the liquid completely, without markedly impairing ionic conduction or self-diffusion of dissolved ions. Macroscopic immobilization of a fluid is not in conflict with mobility on a molecular sceile.
