Method of production of polymers of the series of styrenes is a continuation of low mass

摘要

P is polymerized of styrenes or copolymers, a mixture of styrenes and other vinyl monomers using, as polymerization initiator, an organic peroxide which the decomposition temperature corresponding to ten hours of a half - life is 40 to 70°C, at a rate of 1 to 10% by weight relative to the styrenes, or to the total weight of styrenes and the other vinyl monomers, the polymerization temperature of 50 to 120°C. / p & & p & it is thus obtained of the polymers of the series of styrenes, which are colourless, and which have a low molecular weight, by means of a device of the polymerization is simple and with a high yield and / p
