摘要

本研究第一部分是使有含有壓克力官能基C=C的雙酚A系環氧丙烯酸樹酯作為多元醇、2,2-二氫氧甲基丙酸和聚乙二醇，分別搭配脂肪族且具有六碳環結構的Isophorone diisocyanate (IPDI)、直碳鏈的1,6-hexamethylene Diisocyanate (HDI)以及芳香族的4, 4’-diphenylmethane diisocyanate (MDI)等三種異氰酸鹽合成聚氨基丙烯酸酯。成功合成出含有C=C的雙酚A系環氧丙烯的聚氨酯樹酯。由反應的時間可以得知不同結構特性異氰酸的的反應性MDI＞HDI＞IPDI。由TGA可知芳香族異氰酸鹽之剛性較脂肪族強，而HDI因具有對稱性結構可能產生結晶故推論其剛性為MDI＞HDI＞IPDI。第二部分，則是利用脂肪族異氰酸鹽的NCO官能基與分散藍的NH2反應，利用IR及NMR判定是否形成-NH-CO-NH-反應官能基使異氰酸鹽成功引入具有螢光染料的結構，再與雙酚A系環氧丙烯酸樹酯反應合成具有螢光特性的聚氨酯，以期望可以應用於生醫材料或應用於塗料中。

In this study , we want to use bisphenol A expoxy acrylate which has C=C to be a polyol、DMPA and PEG in order to react with three different diisocyanates , 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane (IPDI)，1,6-hexamethylene Diisocyanate (HDI) and 4, 4’-diphenylmethane diisocyanate (MDI) of aromatic , to synthesis polyurethane.We Successfully synthesized bisphenol A epoxy polyurethane which contain C=C. By synthesized time we can find the Chemical reactivity is MDI＞HDI＞IPDI.By Thermogravimetry Analysis (TGA) , aromatic diisocyanate has the best rigidity because it has two bezene rings. And HDI has a symmetry structure so its degradation temperature is higher than IPDI. The second part is use the NCO functional groups of aliphatic isocyanates and react with the NH2 functional groups of disperse blue 1. By using IR and NMR determine whether the formation of-NH-CO-NH-confirmed to isocyanate structure of the fluorescent dye and then with the bisphenol A epoxy acrylate resin to synthesized with the fluorescent properties of polyurethane, to expect or biological materials can be used in paint.
