An overall picture of the reaction pathways towards the side products and final polymers during the transesterification synthesis of biodegradable aliphatic carbonates (APCs) were delineated for the first time. Catalysed by sodium ethoxide, the normal reaction between α,ω-diols (carbon number n=2–6) and diethyl carbonate generates APC oligomers with propagating terminal alkoxide anions. These anions...
Assembling nanoscale building blocks derived from ultrastrong polymer fibers into ordered architectures should offer an effectively alternative way to access high-performance nanocomposites with extremely high strength and heat resistance for advanced applications. Poly(p-phenylenebenzobisoxazole) (PBO) fibers possess outstanding mechanical and thermal properties among the synthetic organic fibers...
