The total bromine concentration (C _Br, mmol g ⁻¹), the content (Br _(#), 10 ⁻⁵ mol g ⁻¹), the ratio (% #, mol.%), and Br ⁺ desorption peak temperature (T _(#),°C) for β _#(Br) form; the fraction of Br ⁺ (m/z 79 and 81) ion current in TPD-MS analysis (I _Br, %). The I _Br was calculated as the integral intensity with account of HBr ⁺. The content Br _(#) determined by multiplying %#, I _Br and C _Br
