• 中文摘要： 固液型環氧樹脂以半批式進行丙烯酸之變性反應, 所得變性樹脂得利用苯乙烯進行硬化,其硬化反應比環氧樹脂之傳統硬化方式所需溫度為低且硬化時間亦較短。該變性樹脂所製成複合材料具有優良之物性。由攪拌速度、反應溫度及觸媒之效果探討變性反應條件, 並研究其變性反應之動力學, 求得其視活化能為0.13 Kcal/ mole。
• 英文摘要： Modification of solid and liquid epoxy resins was carried out with acrylic acid in semibatch process, and the modified resin was cured with styrene. It was found that the curing temperature is lower and the curing time is shorter than for traditional epoxy resin curing processes. The composite materials prepared from the modified epoxy resin have a higher mechanical strength and a greater electrical resistance. The effects of agitation, temperature and catalysts on modification are investigated, and the kinetics of modifying reaction is also studied. The apparent activation energy of 0.13kcal/mole was obtained from Arrhenius equation.
