| 摘 要： | 通过改变传统的引发体系,采用BF3.(CH3)2O/CF3COOH合成了无色透明且分子量较高的端羟基聚环氧氯丙烷(PECH),利用核磁共振、红外光谱等手段对产物的化学结构进行了详细的分析,同时考察了BF3.(CH3)2O及CF3COOH用量对PECH相对黏度的影响,探讨了TCA提高产物透明度的作用。结果表明,合成了主链以头尾连接为主,头头及尾尾连接为辅的PECH。 |
| 关 键 词： | 端羟基聚环氧氯丙烷 共引发剂 相对黏度 |

| Abstract: | The paper presented the synthesization of hydroxyl terminated polyepichlorohydrin by new coinitiator of CF3COOH/BF3(CH3)2O.The chemical constitution was discussed by methods of IR,1H-NMR and 13C-NMR.And the impact of the amount of the boron trifluoride diethyl etherate and TCA was discussed and the role of increasing relative molecular weight and transparency of TCA was discussed in the paper at the same time.The chemical constitution of PECH indicates that the main chemical constitution of hydroxyl terminated polyepichlorohydrin is H-T,and the subordination chemical constitutions are H-H and T-T. |
| Keywords: | hydroxyl terminated polyepichlorohydrin coinitiator relative viscosity |
