• 中文摘要： 利用IR、ESCA、TGA和動力黏彈性等測試, 對含原冰片烯基尾罩的聚醯亞胺的交連分析。交連後化學結構已在前面文獻中報告。在 N-PMR反應過程, 它的TGA圖在有氧存在下, 重量沒有減少趨勢, 而由ESCA分析, 顯示氧接在 N-PMR鏈上。從儲存模數對溫度曲線, 觀察到當溫度超過先前交連溫度時, 有進一步交連。而N-PMR的主鏈裂解溫度在500.degree.C以上, 又在較低溫時, 即有部份環戊二烯被釋放出來。
• 英文摘要： IR spectra, ESCA, TGA, and the dynamic viscoelastic measurement were employed for investigating the curing of norbornenyl end-capped imide prepolymer (N-PMR). These results sustained that reported in the previous paper. The resulting cured structure was shown. In presence of oxygen, the TGA diagram of N-PMR was fluctuating and the weight loss at higher temperatures was less significant. ESCA spectra of N-PMR suggested that oxygen was linked in polymers. N-PMR is still on cross-linking generally when heating above their prior curing temperature as observed from storage modulus temperature curves. Main chain scission of N-PMR occurred above 500.degree.C and part of N-PMR splitting off cyclopentadiene at lower temperatures was suggested.
