本實驗主要使用擁有兩個末端位置碳碳雙鍵之雙馬來醯亞胺(N,N'-bismaleimide-4,4'-Diphenylmethane, BMI) 與擁有CH2活性氫之1,3-雙甲基巴比妥酸 (1,3-Dimethylbarbituric acid, 13BTA) 和擁有兩個NH活性氫之5,5-雙甲基巴比妥酸(5,5-Dimethylbarbituric acid, 55BTA)進行聚合反應,並使用可促進麥克加成反應(Michael addition reaction)之觸媒以及可抑制自由基反應之抑制劑,將雙馬來醯亞胺與巴比妥酸內包含之兩種競爭反應麥克加成反應與自由基加成反應(Free radical reaction)各別進行其反應動力學研究。
主要使用微分式掃描熱量分析儀(DSC),在各溫度下反應兩小時所獲得之放熱量,經數據處理與計算後選用最適合之反應動力學模型,再利用Arrhenius equation 計算出活化能(Ea)與頻率因子(A);再利用核磁共振光譜儀(NMR)、膠體滲透分析儀(GPC)、熱重/熱示差分析儀(TGA)等儀器,分析並比較其反應性、耐熱性等性質。


This work studied the effects of catalysts on the kinetics of polymerization of N,N'-bismaleimide-4,4'-Diphenylmethane (BMI) with 1,3-Dimethylbarbituric acid (13BTA) or 5,5-Dimethylbarbituric acid (55BTA).The reaction between the two terminal -C=C- groups of BMI with 13BTA containing one CH2 group or 55BTA containing two NH groups were investigated. Addition of catalysts to promote Michael addition reaction and use of inhibitor hydroquinone (HQ) to inhibit free radical polymerization were also studied. In this manner, Michael addition polymerizations of BMI with 13BTA or 55BTA can be studied without the interference of free radical polymerization.
DSC was used to obtain the reaction kinetics data, then data were used to choose the best-fit kinetics model and determine triplet kinetics parameters. NMR, GPC and TGA were employed to study the reactivity of 13BTA and 55BTA.
