1.测定甲基丙烯酸甲酯氧化时,温度及各种加入物如硬脂酸钴、对苯醌、三聚甲醛、丙酮酸甲酯、偶氰双异丁腈及其本身的“过氧化物”等对氧化速度的影响。从而进一步证明此反应的游离基链锁反应的特性。 2.测定共聚[过氧-甲基丙烯酸甲酯]在苯及在醋酸乙酯溶液内各种温度时的分解速度。并用间接方法,测知其单分子分解的活化能为22±1仟卡/克分子。 3.肯定该“过氧化物”具有引发甲基丙烯酸甲酯聚合的能力。观察以此作引发剂的聚合速度及聚合过程中聚合物分子量的变化,并注意到以此引发所生成的聚合物具很高的分子量。
1. Determination of methyl methacrylate oxidation, the temperature and various additives such as cobalt stearate, p-benzoquinone, paraformaldehyde, methyl pyruvate, cyanogen bis isobutyronitrile and its own “peroxide ”And so on the impact of oxidation rate. Thus further demonstrating the reaction characteristics of the free-radical chain reaction. 2. Determination of copolymerization [peroxy-methyl methacrylate] in benzene and ethyl acetate at various temperatures within the decomposition rate. And by indirect method, measured the activation energy of its single-molecule decomposition of 22 ± 1 kcal / mole. 3. Be sure the “peroxide” has the ability to initiate the polymerisation of methyl methacrylate. The rate of polymerization as the initiator and the change in the molecular weight of the polymer during the polymerization were observed, and it was noticed that the resulting polymer was caused to have a very high molecular weight.
