Nano‐sized polyhedral oligomeric silsesquioxane ( POSS ) diol or ethylene glycol ( EG ) as diol monomer was incorporated into hydroxyl‐terminated polybutadiene ( HTPBD ) chain in the presence of fumaryl or thionyl chloride as extenders. Using these polyesterification reactions, two fumarate‐based polyesters and two polyester sulfites were synthesized. Each couple of polyesters and polyester sulfites includes a linear (diol: EG ) and a nanohybrid macromer (diol: POSS ). Full structural characterization was performed using Fourier transform infrared, 1 H NMR and 13 C NMR spectroscopies. Gel permeation chromatography was undertaken to study polyesterification mechanisms by deconvolution of the obtained traces. Finally, differential scanning calorimetry, thermogravimetric analysis and cell culture were performed to evaluate the structure–property relationship for the synthesized macromers in comparison with unreacted HTPBD . © 2016 Society of Chemical Industry
