ABSTRACT

The paper evidences changes of thermal properties of poly(methyl methacrylate) as well as methyl methacrylate copolymers with glycidyl methacrylate (GMA) polymers synthesized classic and comparatively in a magnetic field. Samples of poly(methyl methacrylate) and methyl methacrylate copolymers with different amounts of GMA synthesized by radical emulsion polymerization with or without the presence of a continuous electro- magnetic field, they were thus compared. The thermal behavior was studied by Differential Scanning Calorimetry (DSC) and Thermogravimetry (TGA). The paper evidences the higher Tg as well as the higher thermal stability of the macromolecular chains structures synthesized in the presence of the electromagnetic field.
