A Method for Preparing Rubber Latex Specimens for the Electron Microscope

Abstract
A new method was developed for preparing natural and synthetic rubber specimens for examination with an electron microscope. The technique consisted of mixing latex with a water solution of polyvinyl alcohol and forming a film from the mixture. Electron micrographs of such specimens showed none of the flattening of particles characteristic of the collodion film method and the micrographs were suitable for direct particle‐size measurements.
