采用乳液聚合,以CBr_4为调节剂制得的溴端基聚丁二烯液体橡胶,其结构式为:式中n>>m。该聚合物分子链中有两种溴基。为了测定其中的端基烯丙基溴的含量,必须找出一种反应条件,以便将这两种溴基中的溴相区别。为此,本文在文献的基础上,分别以二溴甲烷和溴丙烯作二溴甲基和端基烯丙基溴的模型化合物,从而建立了 Using emulsion polymerization, CBr_4 as a regulator of bromine-terminated polybutadiene liquid rubber, the formula is: where n >> m. There are two kinds of bromine groups in the polymer chain. In order to determine the content of terminal allyl bromide therein, it is necessary to find a reaction condition in order to distinguish the bromine phases of the two bromine groups. Therefore, based on the literature, dibromomethane and bromopropene were used as model compounds for dibromomethyl and terminal allylbromide respectively to establish
