• 中文摘要： 由回收PET瓶依兩階段製程獲得不飽和樹脂。第一階段將PET在過量二元醇下藉加壓醇解為短鏈多元醇寡分子。第二階段為多元醇寡分子與二元酸聚縮合,再經添加苯乙烯單體而製成不飽和樹脂。由不飽和樹脂各種來源製成為聚縮合樹脂以及FRP積層板加以比較其機械性質。因添加TDT後,各種不飽和樹脂的機械性質改變亦加以討論。
• 英文摘要： Unsaturated polyester resins derived from recycled PET bottle are prepared by using of a two-stage process. The first stage is the glycolysis of PET in an excess of diol under high pressure to produce short-chain polyol oligomers. The second stage is the polycondensation of the polyol oligomers with dibasic acid followed by adding styrene monomer diluent to obtain unsaturated polyester resins. The unsaturated polyester/glass fiber FRP laminates are made by combining glass fiber mat (30%) with three different sources of the unsaturated polyester; one taken from a product in the market one from the industrial PET chips and one from recycle PET bottles. The mechanical properties of these polycondensation resins and FRP laminates are compared with those of a commercial UP product. The effect of the incorporation of 2,4-toluenediisocyanate (TDI) on these polyester resins are also investigated.
