摘要
在 2 0升热聚合反应釜中对中温煤沥青进行热聚合改质处理 ,研究了热聚合改质过程中煤沥青热解缩聚行为 ,讨论了煤沥青结焦值随聚合时间和聚合温度的变化 。
The behavior of pyrolysis condensation of coal-tar pitch during the thermal polymerization modification has been investigated in a reaction still.The variation of coking value of coal-tar pitch with the polymerization time and polymerization temperature has been discussed.The correlation between the coking value and the toluene insoluble during the thermal polymerization modification have been found.
