摘要: 采用3,3′,5,5′-四甲基-4,4′-联苯二酚与环氧氯丙烷在18-冠-6-醚(CE18)为相转移催化剂作用下,利用两步加碱法合成了联苯型环氧树脂(TMBP),在反应温度为80 ℃、反应时间为8 h、NaOH用量为0.2 mol时,产率达83 %。用核磁共振、红外光谱、X射线衍射、热台偏光显微镜和DSC对所制备的产物进行了结构表征。结果表明,合成的产物为TMBP,具有良好的结晶性,熔点为107.8 ℃,在冷却过程中出现液晶态。TMBP熔融黏度极低(0.02 Paos,150 ℃),用TMBP与酚醛环氧树脂(ECN)共混,可降低体系的黏度,从而提高硅微粉的填充量和大规模集成电路封装材料的流动性。

Abstract: Tetramethyl biphenyl epoxy resin (TMBP) was synthesized from 3,3',5,5'-tetramethyl-biphenyl-4,4'-diol and epichlorohydrin via a two-step method using 18-crown-6-ether as a Phase-transfer catalyst. The effect of temperature, reaction time, and phase-transfer catalyst on product yield was investigated. It was found that a maximum product yield of 83 % was obtained at 80 ℃ for 8 h. The chemical structure of TMBP was characterized with 1H-NMR、FTIR、XRD、POM and DSC. DSC showed that the melting temperature of TMBP was 107.8 ℃. POM results indicated that TMBP was a crystalline oligomer and its liquid crystalline behavior appears when cooled down from 120 to 76.2 ℃. TMBP has very low ηa (0.02 Paos at 150 ℃) and can be blended with ortho-cresol novolac epoxy resin(ECN) in order to decrease ηa of epoxy molding composite(EMC). It was concluded that TMBP can be used as a matrix resin for manufacturing epoxy molding compounds for integrated circuit encapsulation.
