Notes:
The coalescence of a poly(vinylidene chloride/methyl acrylate/acrylic acid) latex was found to occur only above the Tg. The various theories of film formation from polymer dispersions attribute latex coalescence to three types of forces: the pressure due to the polymer-air interface, the pressure due to a polymer-water interface, and the pressure due to capillary action. Analysis of the forces indicates that none are sufficient to cause coalescence below Tg while any, or all, may cause coalescence above Tg.
