Gel theory

The Free Volume Theory. This extends the lubricity and gel theories and also allows a quantitative assessment of the plasticization... 

The mode of action of plasticizers can be explained using the Gel theory [35 ]. According to this theory, the deformation resistance of amorphous polymers can be ascribed to the cross-links between active centres which are continuously formed and destroyed. The cross-links are constituted by micro-aggregates or crystallites of small size. When a plasticizer is added, its molecules also participate in the breaking down and re-forming of these cross-links. As a consequence, a proportion of the active centres of the polymer are solvated and do not become available for polymer-to-polymer links, the polymer structure being correspondingly loosened.

Results obtained in mucin-secreting goblet cells, which will be reviewed here, and in histamine-secreting mast cells, which have been presented elsewhere [2], are prompting us to abandon some long-established ideas about packing and release in secretion and to sketch a new hypothesis based on current polymer-gel theory.
