Abstract
Methods for recovering monomers from polymers, such as polyurethanes (including thermoset polyurethanes) include heating the polymer to depolymerize the polymer and release the monomer. The monomer may be directly recovered. The polymer may include a poly(β-methyl-δ-valerolactone) (PMVL) block and the monomer recovered may be β-methyl-δ-valerolactone (MVL).
