  • Patent number: 10988574
    Abstract: A method of producing an oligomer or polymer with carbonate segment chemical structure, the method including the steps of (1) introducing into a reactor high-molecular-weight polyester and reactive oligomer; (2) introducing into the reactor a carbonate compound and a catalyst such that the poly(polyol) reacts with the carbonate monomers by one-pot in situ to produce a crude product; and (3) introducing the crude product into water to obtain an oligomer or polymer with carbonate segment chemical structure. The oligomer or polymer with carbonate segment chemical structure is applicable to automobile manufacturing, wires & cables, and medical equipment.
