| 摘 要： | 以双酚A和溴丙炔为原料,采用相转移催化合成法合成了二丙炔基双酚A醚,利用红外和核磁对其结构进行了表征。采用示差扫描量热法(DSC)对二丙炔基双酚A醚的固化反应历程进行了研究。分别由Kisserger方程和Ozawa方程求得二丙炔基双酚A醚聚合反应的活化能分别为127.3KJ/mol和131.6KJ/mol。用Crane经验方程求得固化反应的反应级数接近于1。研究表明,二丙炔基双酚A醚具有较低的固化反应活化能以及较宽的加工窗口,这有利于二丙炔基双酚A醚树脂的加工成型。

| Abstract: | Dipropargyl ether of bisphenol A was synthesized via phase transfer catalyst reaction. DSC was adopted to study the curing kinetics of dipropargyl ether of bisphenol A and the kinetic parameters were calculated by methods of Kissinger and Ozawa. The results show that the apparent curing reaction order of dipropargyl ether of bisphenol A is 1. curing activation energies are 166.36kJ/mol and 199.36kJ/mol by methods of Kissinger and Ozawa respectively. The lower curing reaction activation energy and wide processing window are conducive to process of dipropargyl ether of bisphenol A. |
