Synthesis and properties of linear polyborazoles. Part I. Condensation of B-dichloro-N-tri-(2,6-dimethylphenyl)borazole and aliphatic diamines

Abstract

The linear polymerisation of B-dichloro-N-tri-(2,6-dimethylphenyl)borazole through the aliphatic diamines, ethylene-, trimethylene-, tetramethylene-, and hexamethylene-diamine has been investigated, and certain properties (range and degree of plasticity, stability in air, hydrolytic and thermal stability) of the linear polyborazoles formed have been compared and related to their structure and degree of polymerisation.
