Volumetric properties of 3-methylbutyl ethanoate with ethyl acrylate, butyl acrylate, methyl methacrylate, and styrene at 25°C

Densities of the binary systems of 3-methylbutyl ethanoate (isoamyl acetate) with ethyl acrylate, butyl acrylate, methyl methacrylate, and styrene have been measured as a function of composition at 25°C and atmospheric pressure using an Anton Paar DMA 5000 oscillating U-tube densimeter. The calculated excess volumes were correlated with the Redlich-Kister equation and with a series of Legendre polynomials. The excess volumes are positive for the binary systems of 3-methylbutyl ethanoate with each of the three acrylate monomers and negative for the system with styrene. The 3-methylbutyl ethanoate + butyl acrylate system exhibits near-ideal behavior.
