Methods：To substitute ＂the trinitrophenol test paper＂ into＂ the trinitrophenol test paper wetted by sodium carbonate test solution＂ on the method of identification. 方法：将原法中“三硝基苯酚试纸”改为“碳酸钠试液湿润过的三硝基苯酚试纸”。
However, some of strong organic acid, chloroacetic acid(CAA), bromoacetic acid(BAA) and 2,4,6 trinitrophenol(TNP) did not enhance the rate of the stable free radical mediated polymerization. 而有机强酸 [氯乙酸 ( CAA) ,溴乙酸 ( BAA) ,2 ,4 ,6-三硝基苯酚 ( TNP) ]并不提高聚合速率
