Chemical synthesis of degradable poly(β-hydroxyalkanoate) (PHA) that can be produced by microorganisms allows the control of solubility, crystallinity, hydrophobicity, degradability, thermal, and mechanical properties by introducing functionality on the side chain. Herein, we synthesized a PHA derivative containing pendant allyl group via anionic ring-opening polymerization of 4-allyloxymethyl-β-propiolactone (AMPL) monomer, prepared from the carbonylation of allyl glycidyl ether. AMPL monomer was subjected to various organocatalysts in bulk to yield a poly(4-allyloxymethyl-β-propiolactone) (PAMPL) in a controllable molecular weight and dispersity. Photoactivated thiol-ene reaction allows the post-polymerization modification of PAMPLs with varying substituents, among which the cross-linked PAMPL films are degraded by the chemical and thermal conditions, and more importantly, under soil and sea water in a wide range of degradation kinetics. |
