| Abstract |
The paper had its origin in the study of the Brillouin spectrum of laser radiation scattered by four acrylic monomer liquids, methyl acrylate (MA), methyl methacrylate (MMA), ethyl methacrylate (EMA), and cyclohexyl methacrylate (CHMA). Basically, this study determined the temperature dependent acoustic velocity and attenuation in the frequency interval 500-1000 MHz, i.e. in the ultrasonic to hypersonic range. Use of this data, in conjunction with other data, such as the specific heat at constant pressure, C(p), and the temperature dependent density allow one to deduce further properties and parameters of the acrylic monomers. The following text discusses the details and includes data measured, or deduced, for three additional acrylic monomers, ethyl acrylate (EA), butyl acrylate (BA), and butyl methacrylate (BMA). The extension of the calculation methods to other liquids of this homologous series is then apparent. (Author) |
