demonstrate a novel synthesis route to TLD by the direct condensation of thiolactic acid (TLA) with Brønsted acid catalysts in the absence of co-reagents or stoichiometric additives. Homogeneous sulfonic acid catalysts afforded a TLD yield of up to 80% directly from racemic TLA. Heterogenizing the catalytic system is challenging in which sulfonic acid containing ion-exchangeresins enabled a maximum

chemically recyclable polymers represents a greener alternative to landfill and incineration and offers a closed-loop strategy toward a circular materials economy. However, the synthesis of chemically recyclable polymers is still plagued with certain fundamental limitations, including trade-offs between the monomer's cyclizability and polymerizability, as well as between polymer's depolymerizability and
