摘要：首先以4,4-联苯二甲醚(BMBP)和2,6-二甲基苯酚为单体、对甲苯磺酸(PTS)为催化剂,合成了联苯基酚单体(BDBP)。将BDBP进行氰化后,成功制备了一种新型联苯基二元氰酸酯(BDBPCy)。利用红外光谱(FT-IR)和质谱(MS)对酚中间体及氰酸酯单体结构进行了表征。通过差示扫描量热法(DSC)、动态热机械分析(DMA)等测试手段考察了固化后树脂的热性能、力学性能、介电性能、耐湿热性及阻燃性能。结果表明:BDBPCy树脂结构中引入的联苯结构,使得树脂在固化后具有良好的热稳定性及自阻燃性能,800°C的质量残留率为42%,玻璃化转变温度为258°C,UL-94垂直燃烧实验测试结果为V-0级别。同时,结构中的大体积联苯基团和邻位甲基基团进一步提高了树脂的介电性能和耐湿热性能。
Biphenyl phenol （BDBP） monomer （BMBP） and 2,6-dimethyl phenol as monomers, was first synthesized using 4,4-biphenyl dimethyl ether toluene-p-sulfonic acid（PTS） as initiator. A new biphenyl cyanate ester resin （BDBPCy） monomer was further prepared by cyaniding BDBP. The molecular structure was characterized via FT IR and MS. The thermal properties, mechanical properties, dielectric properties, water absorption and the flame retardant property of the cured resin were studied via DSC and DMA, etc. Results showed that the cured resin exhibited excellent heat stability and retardant property with the incor poration of biphenyl into the resin structure, residual mass of 420/00 in nitrogen at 800 ℃, glass transition temperature of 258 ℃, class V-0 by UL 94 flame retardant test. Meanwhile, the large size biphenyl and the methyl of the ortho-position in the structure further improved dielectric properties.
