A lab‐scale experimental program was conducted to determine the feasibility of producing vinyl acetate‐ethylene (VAE) emulsion copolymers via a continuous reaction process, using poly(vinyl alcohol), or PVOH, as a protective colloid. A process configuration of multiple stirred‐tanks in series was utilized. Comparisons were made between continuous and batch processes with regard to final‐product properties. As expected, notable differences in the breadths of the particle‐size distributions obtained via the two processes were observed. However, these differences did not appreciably alter product performance in tile‐mortar applications (as measured by plywood‐to‐quarry‐tile adhesive strengths). Additionally, for the continuous process, in‐process and final‐product samples were compared to determine how polymer properties varied with conversion.
