Abstract Precursors with sharp crystalline transition temperature have attracted signifi cant attention in the fi eld of
shape-memory materials; however, seldom have reports been related to amorphous ones with industrial
application prospects. This study introduced a new family of amorphous CO2
-based hydroxyl-telechelic
three-armed oligo(carbonate-ether) triol (Triol) with controllable molecular weight (Mn) and carbonate unit
content (CU), which was coupled with PEG and 1,6-hexamethylene diisocyanate (HDI) to afford crosslinked
polyurethanes (PU) networks with well-defi ned architecture. A crosslinking point was provided by Triol
and PEG was used to afford networks some crystallinity. The resulting networks were characterized… More >
