Racemization on thermal degradation of poly(l-lactide) with calcium salt end structure
Abstract Poly( l -lactide) with calcium salt end structure (PLLA-Ca) is a promising material for PLLA recycling because of the ease of lactide recovery through the unzipping depolymerization process.Expand

Synthesis of rare-metal absorbing polymer by three-component polyaddition through combination of chemo-selective nucleophilic and radical additions.
Sequential three-component polyaddition has been difficult, because the first addition typically consumes the two reactive monomers to produce a stable intermediate that cannot react smoothly withExpand
