摘要

以苯酚及4

4′-二（氯甲基）联苯为单体，盐酸作催化剂经Friedel-Crafts烷基化反应，合成了苯酚-亚联苯型酚醛树脂。利用傅里叶红外光谱（FTIR）、核磁共振（1H NMR、13C NMR）、凝胶渗透色谱（GPC）与热失重分析（TGA）对产物的结构、分子量、分子量分布及耐热性进行了表征与测定。结果表明：经Friedel-Crafts烷基化反应所得到的苯酚-亚联苯型酚醛树脂系邻、对位取代的混合物。随着苯酚用量的增大，苯酚-亚联苯型酚醛树脂的相对分子量逐渐减小，分子量分布逐渐变窄。产物耐热性能优异，起始分解温度能达到340℃。

Abstract

Phenol-biphenylene resin was synthesized with phenol and 4

4′-bi(chloromethyl)biphenyl as monomers and hydrochloric acid as the catalyst by Friedel-Crafts alkylation.The structure of the product was characterized by using Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (1H NMR

13C NMR).Gel permeation chromatography (GPC) and thermogravimetric analysis (TGA) were used to test the molecular weight

molecular weight distribution and heat resistance of the product.The results showed that the phenol-biphenylene resin obtained by Friedel-Crafts alkylation was a mixture of ortho and para isomers.The more the phenol was added

the smaller the molecular weight and the narrower the molecular weight distribution phenol-biphenylene resin would have.The decomposition temperature of the product was 340℃

which gave the product excellent heat resistance.
