  • Patent number: 11555086
    Abstract: The present invention relates to a method of synthesizing hydrocarbon polymers using a deoxygenation reaction, wherein, by deoxygenating polymers including oxygen atom-containing functional groups in side chains thereof to thereby remove the functional groups of the side chains, various block copolymers including polyolefins and hydrocarbon polymers with complex architectures can be synthesized.
    Type: Grant

  • Patent number: 11180626
    Abstract: The present invention relates to a method of preparing a hierarchically porous polymer and a hierarchically porous polymer prepared thereby. The method comprises the steps of: (a) polymerizing an external oil phase of a high internal phase emulsion (HIPE) consisting aqueous droplets to produce a cross-linked block copolymer; (b) obtaining a macroporous polymer with interconnected macropores by removing the aqueous droplets; and (c) treating the obtained porous polymer with a base, thereby obtaining a hierarchically porous polymer having three-dimensional mesopores formed in the macroporous walls. According to the method, the macropore size and mesopore size of the hierarchically porous polymer can all be controlled. The hierarchically porous polymer prepared by the method can easily separate polymers having different sizes, and thus is highly useful in the polymer separation field.
