The thermal behavior of porous bead methyl methacrylate–di(methacryloyloxymethyl)naphthalene (DMN) copolymers was investigated by TG, DTA, and DSC measurements as well as the inverse gas chromatography method using several different molecular probes. TG and DTA results proved copolymer stability up to 250°C. The retention diagrams for all probes used showed the temperature transitions among which one corresponds to glassy transition of amorphous PMMA. The other features observed on the retention diagrams correspond to a segmental mobility of weakly crosslinked copolymer parts.
