The syntheses and the performance of five glycidyl compounds as novel reactive coalescing agents are presented. The reactive coalescing agents were synthesized with moderate yields, structures were verified using spectroscopic methods, and the properties of glycidyl compounds such as boiling points and evaporation rates were measured. The applicability of five glycidyl compounds as reactive coalescing agents was tested in characterized carboxyl functional latex. Properties like pendulum hardness, gloss, and efficiency of the glycidyl compound to reduce the minimum film‐formation temperature (MFFT) of the latex were measured from the cured latex films. The application test results were compared to the commercial nonreactive coalescing agent, Nexcoat™ 795. The films with synthesized reactive coalescing agents with carboxyl functional latex were found to have good pendulum hardness and excellent gloss. Also, the efficiency of three glycidyl compounds in lowering the MFFT of the latex was competitive with the commercial coalescing agent. © 2002 Wiley Periodicals, Inc.
