Fundamental Studies of the Application of Synthetic Resin Latices

VI.Observation of the Diameters of Synthetic Resin Latex Particles

Abstract

The authors have studied the relations between the diameters of synthetic resin latex particles observed under electron microscope and the drying or curing temp.of the latex on the trager.The diameters of the particles dried or cured atΔT<0 (ΔT=drying temp.or curing temp.-film forming temp., Fujii and Otsuka, this journal 12, 93 (1955)) observed from photographs, show true diameters, but atΔT>=0, the diameters increase suddenly.Therefore, to observe the true diameters of the particles under the electron microscope, the latices must be dried under the condition ofΔ<0.
