很早就知道,在烯类单体自由基巨合中,变价金属盐对巨合过程是有影响的,特别是在氧化还原引发体系的自由基巨合体系中,变价金属盐往往是作为引发系统的组成之一。但是变价金属盐,或者更广泛一点说各种金属盐类对自由基巨合的影响及其反应机理如何?这方面工作,过去在国外做了不少的研究,可是到目前为止,尚未研究得很清楚。在均相中,有金属盐参予的烯烃巨合过程中,从其表现的性质来看,是一个比较复 It has been known for a long time that, in the radical polymerization of vinyl monomer radicals, the variable-valent metal salts have an effect on the process of macrocompassing. Especially in the radical-based system of redox-initiating systems, the variable-valent metal salts are often used as initiators One of the components of the system. However, the price of metal salts or, more generally, the effects of various metal salts on free radical gigahertz and their reaction mechanisms? Much work has been done in foreign countries in the past, but so far it has not been studied very clear. In the homogeneous phase, there is a metal salt involved in the process of olefin giant, from the nature of its performance, is a more complex
