In NMRP, the polymerization of MMA, the polymerization of St and the copolymerization of MMA with St were distinctly accelerated by the addition of a small amount of MN. The polymerization proceeds in a living fashion as indicated by the increase in molecular weight with the increase of time and conversion and a relatively low polydispersity. It has been found that the addition of MN results in a nearly one hundred times higher rate of the polymerization of MMA, a nearly twenty times higher rate of the polymerization of St and a nearly fifteen times higher rate of the copolymerization of St and MMA.

一 高中时代，年级里有个特别让人无可奈何的男生。男生的家境好，成绩好，人缘好，多才艺，相貌也生得不差。有他在，全校第一不作他想。 学习拼不过，家境拼不过，才艺拼不过。面对这样的人，凡人如吾辈，多少是含着嫉妒，兼带一些绝望的。 但不知何时起，一则流言在学校里渐渐传开了。 “你知道吗？他好像是个同性恋。” 某次期中考的家长会上，老师再次公开表扬了该名男生。冷不防，某位母亲阴阳怪气地冒了一句：
