Description

Methyl methacrylate (MMA) polymerized in terms of hydroxylamine-H2O2 redox system in water at 30°C. The rate of polymerization; was maximum aj pH 2.0. The mole ratio of reacted H2O2 to hydroxylamine was about 3 in the absence of MMA, whereas in the presence of MMA it was 1/2. At the beginning of polymerization, the decreasing rate of hydroxylamine in the presence of MMA was nearly equai to that in the absence of it. The nitrogen Content in a polymer was 1.43 g atom per mole of a polymer in a certain case. These results suggested that the reaction of hydroxylamine With H2O2 proceeds by means of free radical process and forms free radicals containing nitrogen ; this reaction rnechanisin was also discussed.
