An apparatus has been constructed wherein the transparency of a glass/polymer sheet/glass assembly undergoing vacuum de‐airing can be monitored continuously. Experimental conditions can be varied independently, such as vacuum level, cold (ambient) de‐airing time, and oven temperature. The behavior of polyvinyl butyral and an ionomeric interlayer (SGP) with different rheological properties and surface roughness were studied using various de‐airing conditions. Initial results show that the clarity of the assembly is a monotonically increasing function of time in the oven at a given vacuum level. All assemblies made from these interlayers became clear with sufficient vacuum time at ambient temperature. The assembly from polyvinyl butyral with protrusion‐type surface pattern clears up faster than that with indentation‐type. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 80: 521–528, 2001
