Polycondensation of diesters with BHETA for PEA production.

Diester	PEA	Mn[a] [g mol−1]	Đ[a]	Tg[b] [°C]	Td‐5[c] [°C]	Td‐50[c] [°C]
DMSu	PEA(1)	1750	3.36	118	296	392
DMAd	PEA(2)	2150	3.72	114	293	397
DMSe	PEA(3)	3150	2.91	98	293	388
DMFDC	PEA(4)	2450	3.24	126	275	345

Reaction conditions: BHETA (0.23 mg, 0.92 mmol), diester (0.13–0.21 g, 0.92 mmol) and Ti(OⁱPr)₄ (400 ppm, stock solution, 20 μL mL⁻¹ in toluene). Polycondensation step conducted at 210 °C for 3 h under a dynamic vacuum (<1 mbar). [a] Determined via SEC analysis in N,N‐DMAc with 0.1 % w/v LiBr. [b] Determined by DSC analysis. [c] T _d‐5 and T _d‐50 values refer to 5 % and 50 % weight loss respectively during TGA analysis under an argon atmosphere.
