Densities and excess volumes of the binary systems of butyl methacrylate with acetonitrile;  acetic acid, benzene, 1,2-dichlorethane, and hexane have been measured as a function of composition at 293 K and atmospheric pressure by pycnometric method. The measured excess volumes were correlated by polynomials. The partial molar volumes were calculated by experimental data.

Density and excess volume of the binary systems of iso-buthylmethacrylate with acetonitryle and benzene have been measured as a function of concentrations at 293 K and
atmospheric pressure by pycnometric method. The values of excessive and partial molar volumes of the components were calculated. The excess volume for the acetonitryle – isobuthylmethacrylate system receives negative values and for
the benzene system – isobuthylmethacrylate – positive values.
