测定了有机过氧化物与N-甲基-N-2-羟乙基苯胺(HMA)体系引发MMA聚合的动力学方程和聚合表现活化能。由过氧化物/HMA/MNP的ESR波谱证实芳叔胺HMA中,与氮原子相连的亚甲基的氢被摘去形成相应的碳自由基,它能引发单体聚合成为聚合物的端基。这也由聚合物的UV光谱所证实,由实验结果提出这类体系的引发机理。
The kinetic equations and polymerization activation energies of MMA initiated by organic peroxide and N-methyl-N-2-hydroxyethyl aniline (HMA) system were determined. From the ESR spectrum of peroxide / HMA / MNP, it was confirmed that in aromatic tertiary amine HMA, the hydrogen of the methylene attached to the nitrogen atom is taken off to form the corresponding carbon radical which initiates the polymerization of the monomer to the end of the polymer . This is confirmed by the UV spectrum of the polymer. The experimental results suggest the initiation mechanism of these systems.
