Acrylic acid (AA) and its esters are monomers which can easily be polymerized. In order to avoid the unintentional polymerization during the manufacture and storage, the acrylic esters are stored under air-atmosphere to which 15 ppm (g g(-1)) hydroquinone monomethylether (MeHQ) has been added. The consumption of the stabilizers, oxygen (O-2) and MeHQ, play an important role in the prognosis of the stability of the monomers. In earlier works the O-2/MeHQ-consumption of acrylic acid during the inhibition period without radical-starter-addition was examined [1]. In this paper it could be shown that the examinations on acrylic acid are not transferable to different acrylic esters. The O-2-consumption rates in the acrylic esters are approximately ten times smaller than in acrylic acid, depending on temperature and monomer. The inhibition periods of the acrylic esters are about the factor ten greater in comparison to acrylic acid. A correlation between the concentration of the C=C double bond in the esters and the O-2-consumption is possible with the measurements of the O-2-consumption in the different acrylic esters as a function of temperature. The O-2-consumption of any acrylic ester can be calculated in this way on the basis of the C=C double bond concentration. The same applies to the inhibition period (the time up to the start of the polymerization). An estimation of the stability is possible with these two parameters.
