  • Patent number: 9458287
    Abstract: A process for producing an aliphatic polyester, comprising: subjecting at least two serial stages of bulk-phase ring-opening polymerization and a solid-phase polymerization step, wherein a cyclic ester held in a dry air atmosphere is supplied to a first reactor to perform a first stage polymerization, thereby obtaining a partially polymerized molten product, and the resultant partially polymerized molten product is supplied to a second reactor held under a dry inert gas atmosphere to perform a second stage polymerization. As a result, the production efficiency can be improved, while maintaining excellent properties of the aliphatic polyester product.

  • Publication number: 20150148499
    Abstract: A flame retardant block copolymer is prepared from renewable content. In an exemplary synthetic method, a bio-derived flame retardant block copolymer is prepared by a ring opening polymerization of a biobased cyclic ester and a phosphorus-containing polymer. In some embodiments, the biobased cyclic ester is lactide. In some embodiments, the phosphorus-containing polymer is a hydroxyl-telechelic flame retardant biopolymer prepared by a polycondensation reaction of a biobased diol (e.g., isosorbide) and a phosphorus-containing monomer (e.g., phenylphosphonic dichloride). In other embodiments, the phosphorus-containing polymer is synthesized from a dioxaphospholane monomer.
