The reactions which occur when clay is heated are complex and are rendered still more difficult to study by the apparent polymerization of the alumina formed.
One may easily understand what an important role is played by this alternate polymerization and disintegration in the phenomena of life.
The osmotic pressure varies in the same manner, diminishing with polymerization and augmenting with the disintegration of the micellae.
The phenomenon of polymerizationappears to be reversible.
Such a difference may be accounted for by the difference in the quantity of heat released by the polymerization to double-molecules or larger molecule-complexes.
For substances with a small polymerization heat the degree of association will continually decrease if we move along the border-curve on the side of the saturated vapour in the direction towards lower T.
Moreover, the influence of the polymerization (association) on the liquid volume appears to be small, so that we may even attribute the value 1/3 to substances which are not normal.
For water and alcohols this geometrical locus will be found on the other side of the border-curve, and the polymerization heat will be small, i.
Bone has shown that when exposed for some time to the sun's rays it undergoes certain polymerization changes which lead to the deposition of a film of heavy hydrocarbons on the surface of the tube.
Under these conditions the absence of polymerizationand the washing of the nascent and finely divided bubbles of gas by the limewater in the generator yield acetylene of a degree of purity unapproached by any other form of generator.
At the same time, oxidizing and reducing reactions probably occur within the bean, as well as some polymerization and inter-reactions.
Residue on Evaporation Not over 2% Polymerization Not over 5% should remain unpolymerized at end of half hour Flash-Point Over 40.
The glucose formed, it is admissible that a new polymerization with elimination of water produces starch.
Oxidation, dehydration and polymerization have all been suggested, but there is little direct evidence.
