Notes:
An apparatus has been constructed for measurement of the minimum filming temperature (MFT) of a polymer emulsion. The apparatus consists of a metal bar along which a temperature gradient may be maintained. Recessed channels are provided in which emulsion samples are spread and allowed to dry. Eight thermocouple stations along the bar are connected to a continuous recorder. Following drying of the film, the minimum temperature at which a continuous film is formed is determined. Testing of the apparatus on one emulsion examined under a variety of conditions and on samples of varying composition has demonstrated the reliability, versatility, and utility of the apparatus.
