style="text-indent:25px">四氫呋喃丙烯酸酯是一種重要的特種丙烯酸酯，分子中的環(huán)狀醚基比直鏈醚基更富于活性，醚鍵的α-位碳上的氫也有一定活性，特殊結(jié)構(gòu)賦予其后續(xù)產(chǎn)品特殊的性質(zhì)。以TFA作為共聚成分的丙烯酸樹脂與氨基樹脂并用時，可在較低溫度（100℃左右）下固化。同時TFA分子價鍵有一定的柔韌性，與其它樹脂并用可以起到增塑的效果。此外，TFA還可以作為單體稀釋劑應用于紫外光（UV）固化產(chǎn)品，其特殊的環(huán)醚結(jié)構(gòu)使其與其它單官能度單體相比對大多數(shù)底材具有更好的附著力，同時有著低收縮性、強耐候性、強耐磨性和強耐水性，因此被普遍應用于光固化的粘合劑、涂料、油墨等領域。隨著材料科學的日益發(fā)展，可以預計TFA會有越來越普遍的應用。2-甲基四氫呋喃沸點較高。</p><div
