Abstract
"Film formation from thermoplastic resin solutions Is Influenced by secondary intermolecular forces. Consider what may happen when organic coatings change from a liquid to a solid state. In the liquid state it is logical to consider the linear polymer molecules as agglomerates being dispersed in the volatile component rather than being present In solution. These molecular agglomerates are referred to as micelles. They have various degrees of orientation depending on the extent and the location of dipole forces in both polymer and solvent molecules.
When a coating is applied the solvent starts to evaporate and the micelles are driven closer together. Orientation of the micelles will occur throughout the mass and at the two interfaces, that is coating-substrate and coating- air, provided that the solvent does not evaporate so rapidly that the molecules are immobilized before they can orient to the best advantage for maximum film strength.
Electrostatic effects are transmitted through the chain, largely by electron polarization, as well as through the solvent largely by orientation polarization in the case of polar solvent. If a method could be devised whereby molecular orientation was induced, it might have an effect on water vapor and ion permeation through films of linear polymer such as vinyls and chlorinated rubber.
It is intended in this thesis to show what effect, if any, the rate of evaporation of solvents has on the moisture permeability of linear polymer films, as evidenced by underfilm corrosion of iron vapor deposited on glass panels"--Introduction, pages 1-2.
