本文通过在酚醛树脂中引入多环酚，提高了酚醛树脂的残碳率，并分析了环酚对残碳率的影响，同时通过实验证明主链结构中的醚键和小侧基将明显降低树脂的残碳率。
The polycyclophenol was introduced into standard ph enolic resin and higher char yield was obtained at 900℃.Also by t esting differe nt resins with main structures and those from different reaction temperature,it proves that the ether and small side group will affect the final char yield greatly.
