以双环戊二烯与甲基丙烯酸为原料,在三氟化硼乙醚络合物催化剂的作用下,合成了双环戊二烯甲基丙烯酸酯(DCPMA),并用~1HNMR、FT-IR对产品进行了表征分析。结果表明:当n(甲基丙烯酸):n(双环戊二烯)=1.2:1、催化剂三氟化硼乙醚的加入量为0.6%、阻聚剂对苯二酚加入量为0.4%时,产品收率达52.5%。将DCPMA用于紫外光固化涂料中,与丙烯酸羟乙酯、甲基丙烯酸羟乙酯、2-苯氧基乙基丙烯酸酯、丙烯酸异冰片酯等4种单官能度的单体相比,涂料的固化收缩率低、固化膜的耐磨性好、附着力强、热稳定性高。
Dicyclopentadiene methacrylate (DCPMA) was synthesized from dicyclopentadiene and methacrylic acid under the action of boron trifluoride etherate complex catalyst. The product was characterized by ~ 1HNMR and FT-IR Characterization analysis. The results showed that when the content of n (methacrylic acid): n (dicyclopentadiene) = 1.2: 1, the dosage of boron trifluoride diethyl etherate was 0.6% and the content of hydroquinone was 0.4% The product yield reached 52.5%. DCPMA used in UV-curable coatings, and hydroxyethyl acrylate, hydroxyethyl methacrylate, 2-phenoxyethyl acrylate, isobornyl acrylate and other four kinds of monofunctional monomers, the coating The curing shrinkage is low, the wear resistance of the cured film is good, strong adhesion, high thermal stability.
