The reaction mechanism and kinetics of PMR 15 resin (polymerization of monomeric reactants) were studied at low and room temperature using models thoroughly characterized by nuclear magnetic resonance (1H, 13C liquid and solid state) and liquid chromatography. The results indicate a difference in reactvity of the esters at room temperature and competing reactions that lead to large variations in resin pot life structure, with the detection of amide, ester, imine and amine.
