Structure of a boron-containing bisphenol-F formaldehyde resin and kinetics of its thermal degradation

Abstract

The structure and thermal degradation of a boron-containing bisphenol-F formaldehyde resin (BBPFFR) synthesized by the formalin method have been studied. The results showed that a six-membered ring containing boron–oxygen coordinate linkage was formed in the thermosetting process, and the coordinated oxygen atom was provided by the phenolic hydroxyl. The degradation of this resin began with the oxidation and breakage of ether linkages and carbonyl groups. The kinetic parameters of thermal degradation were determined by thermogravimetric analysis.
