本文以(?)(?)与NaOH的克分子比在1∶2.5以上进行部份水解,制备(?)分析其中(?)与(?)的含量,然后补加(?)配成各种比例进行钠盐溶液法共缩聚,并研究了缩聚反应的各种条件,体系中存在着(?)及(?)[Ⅲ]三种单体,其端基活性不等,酚钠盐活性是[Ⅱ]>[Ⅰ],氯端基活性是[Ⅲ]>[Ⅰ],三者在体系中比例不同,不但使起始聚合速度不同,而且聚合物性能相差较大,[Ⅲ]过量时聚合物性能最好。
In this paper, the (?) (?) And NaOH molar ratio above 1: 2.5 for partial hydrolysis, the preparation of (?) And (?) Content, and then add (?) Dubbed various Ratio of sodium salt solution copolycondensation, and studied the conditions of the polycondensation reaction, the system exists (?) And (?) [III] three monomers, the terminal activity of the phenolic sodium activity is [Ⅱ]> [Ⅰ], the activity of the chloride end group is [Ⅲ]> [Ⅰ], the three different proportions in the system, not only the initial polymerization rate is different, and the polymer performance difference between the larger, [Ⅲ] The best polymer performance.
