本實驗是以合成自行架橋型之硫化聚氨酯(Polythiourethane)為主要目的。以雙官能基之環氧樹脂(DGEBA)為主體，利用末端的環氧基(Epoxy)和二硫化碳(Carbon disulfide)進行開環反應，使末端形成含硫之五雜環結構(Thiocarbonate)，再以雙官能基胺類(JeffamineD-2000、PDMS-diamine)進行鏈延長，使側邊懸掛硫醇基(-SH)，利用硫醇基的氧化作用而成硫-硫鍵(S-S bonds)自行架橋系統，形成具硫化甲酸脂官能基的薄膜，而達到對聚胺樹脂的改質。 In this research, a cross self-curing system of polythiourethane was the main target. The five-membered dithiocarbonate was obtained from the epoxy-rings (DGEBA) which reated with carbon disulfide(CS2). Furthermore, the dithiocarbonate reacted with various diamines (Jeffamine D-2000, PDMS-diamine) to give the products, poly(thiolthiourethanes), and the S-S bonds produced by the auto-oxidation of pendant thiol group.
