Abstract: Described herein are cyclic polymers, including ultrahigh-molar-mass (UHMM, >2 million Da) cyclic polymers. These cyclic polymers can be prepared via catalyst-mediated (e.g., superbase-mediated) ring-opening polymerization followed by macromolecular cyclization triggered by protic quenching. This proton-triggered linear-to-cyclic topological transformation enables selective, linear-polymer-like access to desired cyclic polymers, including those with UHMM surpassing 2 MDa and/or possessing a dispersity (Ð) of 1.4 or less. In addition, these methods can eliminate the need for stringent conditions such as high dilution to prevent or suppress linear polymer contaminants. These cyclic polymers can exhibit not only much enhanced thermostability and mechanical toughness, and can also be quantitatively recycled back to monomer under mild conditions.

Abstract: Polyhydroxyalkanoates (PHAs) have attracted increasing interest as sustainable plastics because of their biorenewability and biodegradability in the ambient environment. However, current semicrystalline PHAs face three long-standing challenges to broad commercial implementation and application: lack of melt processability, mechanical brittleness, and unrealized recyclability, the last of which is essential for achieving a circular plastics economy. Here we report a synthetic PHA platform that addresses the origin of thermal instability by eliminating ?-hydrogens in the PHA repeat units and thus precluding facile cis-elimination during thermal degradation. This simple ?,?-disubstitution in PHAs enhances the thermal stability so substantially that the PHAs become melt-processable. Synergistically, this structural modification also endows the PHAs with the mechanical toughness, intrinsic crystallinity, and closed-loop chemical recyclability.
