聚甲基丙烯酸甲酯的热裂解研究,有过不少的工作。N.格雷赛(Grassie),H.W.米耳魏耳(Melville),S.L.梅多尔斯基(Madorsky)和С.Е.勃列斯列尔(Бреслер)等曾对它的裂解机理、动力学作了详细的研究。在这些工作中指出:由于在聚合甲基丙烯酸甲酯时动力学链的中断,主要是大分子自由基发生歧化反应所致,因而使形成的大分子的一端含有一个双键,这就使得聚甲基丙烯酸甲酯存在着二个不同的裂解机理。在温度低于300°时裂解从含有双键的链 Polymethyl methacrylate pyrolysis research, have a lot of work. N. Grassie, HW, Melville, SL, Madorsky, and С.Е. Brezl ерелер have documented their cleavage mechanism, kinetics A detailed study. In these efforts, it was pointed out that due to the discontinuation of the kinetic chain during the polymerisation of methyl methacrylate, mainly due to the disproportionation reaction of the macromolecular free radicals, one end of the macromolecule formed contains a double bond, There are two different cleavage mechanisms for methyl methacrylate. Cracking from double bond-containing chains at temperatures below 300 °
