【摘要】 用热失重非等温法对不同甲醛、苯酚摩尔比的酚醛树脂进行了热降解动力学研究。结果表明,甲醛、苯酚摩尔比为1.5时,酚醛树脂的热降解活化能最高,耐热性最好。更多还原

【Abstract】 The kinetics of thermal degradation of three phenolir resins which ratio of formaldehyde and phenol are differnet have been studied by thermal-grarimery. When the mol ratio of formaldehyde and phenol is 1.81 the phenolic resin has the highest activation energy of heat degradation and the best heat restantance.更多还原
