通过烯丙基邻苯二甲酸与具有硫原子的双酚反应，合成了与邻苯二甲酸二烯丙酯（DAP）树脂反应以具有烯丙基的含硫烯丙基酯。将含硫烯丙基酯化合物与DAP树脂共混以改善对铜的粘合性能。通过用含硫烯丙基酯化合物改性，提高了对铜的T剥离粘合强度和搭接剪切粘合强度。特别地，当树脂用具有二硫键（-S-S-）的烯丙基酯化合物（DADS）改性时，粘合强度大大提高。通过傅里叶变换红外光谱（FTIR）分析，发现硫原子位于铜表面，从而提高了界面结合强度。DADS改性DAP树脂固化物的玻璃化转变温度（Tg）和热分解温度（Td）随DADS浓度的增加略有降低。由于DADS改性DAP树脂的交联密度比DAP树脂小，因此T_2降低。此外，从热重分析，用DADS改性的DAP树脂的Td的降低是因为DADS可能热解。© 2013化学工业协会
Sulfur‐containing allyl ester, which reacts with diallyl phthalate (DAP) resin to have allyl groups, was synthesized by the reaction of allyl phthalic acid with bisphenol having sulfur atoms. The sulfur‐containing allyl ester compound was blended with DAP resin to improve the adhesive properties to copper. By modification with sulfur‐containing allyl ester compound, the T‐peel adhesive strength and the lap shear adhesive strength to copper was improved. In particular, the adhesive strength was greatly improved when the resin was modified with the allyl ester compound having a disulfide bond (−S−S−) (DADS). It is concluded that this result is due to the improvement of the interfacial adhesive strength because the sulfur atom was found to be located in the surface of the copper by Fourier transform infrared (FTIR) analysis. The glass transition temperature (Tg) and the thermal decomposition temperature (Td) of the cured DAP resin modified with DADS slightly decreased with increasing concentration of DADS. The lowering ofTgis because the crosslinking density of the DAP resin modified with DADS is smaller than that of DAP resin. Moreover, from thermogravimetric analysis, the lowering of Td of the DAP resin modified with DADS is because DADS is likely to pyrolyze. © 2013 Society of Chemical Industry
