合成了高固体含量（〉85%）的线性酚醛树脂,经凝胶渗透色谱/多角度激光光散射（SEC/MALLS）联用仪测定其数均分子量为1577,且分子量分布范围较窄,-Mw/-Mn仅为1.127。采用差示扫描量热（DSC）分析技术在50℃~300℃温度范围内,以不同的升温速率（2.5℃/min、5℃/min、7.5℃/min和10℃/min）研究了该酚醛树脂的固化反应过程。结果表明,该高固体含量线性酚醛树脂的凝胶化温度Tgel=110.61℃,固化温度Tcure=129.14℃,后处理温度Ttreat=146.96℃;根据Kissinger方程、Ozawa方程和Crane方程以及n级动力学模型确定该树脂的固化动力学方程为dα（t）/dt=2.09×1017（1-α）0.95exp（-2.10235×104/T）。
Novolac-type resin with high solid content（85%） was synthesized,of which number average molecular weight is 1577 and distribution is narrow.The curing process was studied by differential scanning calorimetry（DSC） at different heating rates of 2.5 ℃/min,5 ℃/min,7.5 and 10 ℃/min between 50 ℃～300 ℃.The gelation temperature,curing temperature and post processing temperature of the resin are 136.68 ℃,163.16 ℃ and 197.39 ℃ respectively.According to Kissinger equation,Ozawa equation,Crane equation and the n-level kinetic model,the curing kinetic equation is dα（t）/dt=2.09×1017（1-α）0.95exp（-210235×103/T）.
