| 摘 要： | 采用滴定分析法测定不饱和聚醚的双键保留率,以烯丙醇聚氧乙烯基醚为例,分析了影响其测定的多种因素.结果表明用该方法(乙酸汞与不饱和聚醚反应)测定不饱和聚醚双键保留率是非常实用的,并根据测定结果可知,取样多少以及试样的pH值对测定有影响.

| Abstract: | The double bonds retention rate of unsaturated polyether was determined by titrimetric analysis,moreover,taking polyoxyethylene allyl ethers for example,the many reasons effecting the determination results were dicussed.The results show that the method(the reaction of mercuric acetate and unsaturated polyether) was very useful in determining double bounds retention rate.The factors affecting determination results are the amount of different samples and different pH value. |

| Keywords: | unsaturated polyether titrimetry the double bonds retention rate superplasticizer |
