本研究已成功合成出含矽氧烷與亞醯胺的氰酸酯，並以此新型的氰 酸酯來硬化環氧樹脂。為了探討環氧樹脂與氰酸酯熱硬化行為，以DSC 和FT-IR相互配合使用，證明了此硬化行為的正確性。證實環氧樹脂與氰 酸酯的反應中，氰酸酯會先形成triazine，再與環氧基形成isocyanurate及 oxazolidinone的結構，最後才重組，而不是一開始就與環氧基進行交聯。
氰酸酯結構於主鏈上同時含有柔軟的矽氧烷和硬質之亞醯胺基，其材料 上具有較高的Tan δ波峰而達到增韌的效果，同時又可以保有相當高的玻 璃轉移溫度(Tg)。亞醯胺基團亦使材料展現良好的耐熱性質，其結構減緩 了材料的裂解速率。TMA測試得知，氰酸酯當量比的增加，降低熱膨脹 係數，而有較佳的尺寸安定性。介電常數方面，由於交聯網絡複雜或其 分子量大，產生未反應的cyanate基數目甚多，產物的極性提高而使介電 常數偏高，為降低介電常數可由分子結構的設計加以探討。
