Abstract
We synthesized and characterizated two bromine containing monomers, 2-(2-bromopropyloxy) ethyl methacrylate (BPEM) and 2-(2-bromoisobutyriloxy) ethyl methacrylate (BIEM), to be used as radiopaque agents in acrylic bone cements. Using methyl methacrylate (MMA) and each one of the bromine containing monomers in different concentrations we have synthesized ten copolymers. The copolymerizations were carried out directly in the thermostatic, cell of an NMR Spectrometer. Analyzing the 1H-NMR spectra, we have determined the reactivity ratios of the monomers. Preliminary studies showed that acrylic bone cements which include in the liquid phase these bromine containing acrylic monomers, have a very good radioopacity. Keywords: bromine containing monomers, copolymerization, parameters of reactivity
