• The mechanochemical behavior of methacrylamide was investigated at room temperature and at static pressures of up to 15 kbar. The determinations of the IR spectrum, the ESR signal, the X-ray diffraction pattern, and the molecular weight by GPC apparatus confirmed that the reaction products were amorphous polymethacrylamide. The reaction of methacrylamide under conditions of high pressure combined with simultaneous shear deformation(HP+SSD) is a free radical polymerization. The concentration of radicals of polymethacrylamide and the relation between the conversion and the shearing degree suggest that an acrylamide crystal is less stable than one of methacrylamide. Methacrylamide was not reached 100% conversion even at about 2π rad shearing.
