【摘要】 本文介绍了一种缩醛法合成对叔丁基酚醛树脂的新方法。采用正交试验考察了反应参数对树脂的软化点、分子量和酚转化率的影响,确定了树脂最佳合成条件,并用红外光谱(IR)和核磁共振(NMR)表征树脂结构。更多还原

【Abstract】 A new approach to prepare para-tertiary butyl phenolic resin by acetal reaction has been devel-oped.By using the orthoganol tests,the effectsof reaction condition on the softening point,molecular weight of the resin and conversion ofphenoLs have been investigated to obtain the opti-mum reaction conditions.The resin structure wascharacterized by 1R and NMR.更多还原
