Abstract
Phenol zinc acetate dihydrate and paraformaldehyde are firstly performed to synthesize thermoplastic phenolic resin PR then phenylboronic acid PBA and other two boron compounds 4hydroxymethyl phenylboronic acid boronic acid are introduced to fabricate the boroncontaining thermoplastic phenolic resins BPRs The corresponding molecular structure softening points thermal decomposition temperature and char yield ratio of the BPRs are characterized and investigated by FTIR NMR XPS and TGA Compared to pure thermoplastic PR all the BPRs present relatively higher softening points more excellent thermal decomposition temperature and higher char yield values BPRa exhibits the optimal thermal decomposition temperature T 5 of 3174 °C and char yield ratio at 800 °C 696 The authors are grateful for the support and funding from the Foundation of National Natural Science Foundation of China No 51403175 Shaanxi Natural Science Foundation of Shaanxi Province No 2015JM5153 Open Fund from National Defense Science and Technology Key Laboratory No 2015AFDL018 and the Fundamental Research Funds for the Central Universities Nos 3102015ZY066 and 3102015BJIIJGZ020
