• 中文摘要： 環氧樹脂網狀體具有優異之物理及化學性能，在工業上之應用，有時要求更高溫之抗熱性。為了改善抗熱性在本研究利用合成方法，使無機化合物和聚合物化學結合，以代替通常之複合體即無機化合物以物理方法分散於聚合基體“方法為先合成酣醛樹脂與鹽類以適當之溶劑溶解，再與環氧樹脂溶液混合加熱使之形成網狀體；另一法為先合成一般之環氧樹脂，再以合成方法使末端變為酣基之環氧樹脂，然後用合成方法使氫原子被其他原子取代，再與酣醛樹脂溶液混合，加熱使之形成網狀體“在本研究利用黏彈性測定法，測定Tg和轉移活性能，用來比較環氧樹脂網狀體之抗熱性。從研究結果知以合成方汰使環氧樹脂或架橋劑含Chelate均可使環氧樹脂網狀體之抗熱性提高，但需留意應用適當之合成方法及形成網狀體之過程，成份是否具有熱安定性。
• 英文摘要： For improvement of heat resistance of cured epoxy resin, synthetic me-thod is utilized to bonding inorganic material and organic polymer chemi-cally instead of general composite, in which inorganic compound is dispersedin polymeric matrix, One method of introducing chelates in network ismixing resol type phenol-formaldehyde condensate and salt solution first,then mixing with epoxy resin solution, following with heating; another me-thod is synthesizing phenolic hydroxy terminated epoxy resin first, thenreplacing hydrogen atom with other atoms, and mixing with phenol-formal-dehyde condensate solution, following with heating. For testing heat resis-tance of network, viscoelastic measurement is applied. It is found that: 1．Introducing of chelates in curing agent or epoxy resin will improve theheat resistance of networks. 2. Care must be paid to proper synthetic me-thod and stability of ingredients for formation of network containingchelates.
