WebDec 7, 2024 · The number-average molecular weights ( Mn s) of the resultant polyesters reached up to 20.4 kg/mol when copolymerization was carried out using TEB/ t -BuP 1 (1/1, in molar ratio) at 30 °C. Keywords: succinic anhydride; propylene oxide; aliphatic polyester; organoborane; Lewis base Graphical Abstract 1. Introduction Phosphazene bases are strong non-metallic non-ionic and low-nucleophilic bases. They are stronger bases than regular amine or amidine bases. Protonation takes place at a doubly bonded nitrogen atom. Related to phosphazene bases are the Verkade bases, which feature P(III) with three amido substituents and a transannular amine.
