Table 1. Molecular and Thermal Properties of HBPs (P5a–c)^a.

	Mn (g mol–1)	Mw (g mol–1)	PDI	Tg (°C)	T10 (°C)	Tmax (°C)	CY (%)
P5a	4 494	14 435	3.2	223	354	290, 402	60
P5b	3 761	12 920	3.5	213	317	300, 406	50
P5c	3 282	11 443	3.5	209	318	325, 422	50

^aM_n, M_w, and PDI were determined by GPC in THF. T_g (glass-transition temperature) was measured from the second heating DSC curve and T₁₀ and T_max are the temperatures for 10% weight loss and maximum decomposition rates, respectively, according to the TGA data. Char yield (CY) at 600 °C was measured by TGA.
