We
report the rapid, one-pot synthesis of functional polycarbonates
derived from renewable alcohols (i.e., glucose tetraacetate, acetyl
isosorbide, lauryl alcohol, and ethanol) and a cyclic carbonate bearing
an imidazolecarboxylate. This tandem functionalization/ring-opening
polymerization strategy can be performed on multigram scale and eliminates
the need for rigorous purification and specialized equipment. A wide
range of glass transition temperatures (T
g) was accessible from these renewable pendant groups (>75 °C T
g window). We also synthesized several statistical
copolycarbonates to show the thermal properties can be tailored with
this tandem method. Additionally, we demonstrate a circular polymer
economy via chemical recycling to a cyclic carbonate precursor. This
work may facilitate development of sustainable polycarbonates with
tailored properties that work toward eliminating plastic waste streams.
We demonstrate computational insight and radical ring opening polymerization of a fungi-derived thionolactone, thionoisochromanone (TIC), to create homo-, block-, and statistical copolymers under entirely free radical conditions.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
