  • Oligomer or polymer with carbonate segment chemical structure
    Patent number: 11180611
    Abstract: An oligomer or polymer with carbonate segment chemical structure, whose structure is expressed by the formula wherein R1 is a functional group derived from a polyol, a polyester polyol or a polyether polyol. The oligomer or polymer with carbonate segment chemical structure is applicable to automobile manufacturing, wires & cables, and medical equipment.
    Type: Grant
    Filed: August 7, 2019
    Date of Patent: November 23, 2021
    Assignee: J & A TECHNOLOGY CORPORATION
    Inventors: Jiang-Jen Lin, Tzong-Ming Lee, Chyi-Ming Leu, Sheng-Yen Shen, Hsin-Chung Wu, Hsuan-Hao Tien
  • Method of producing oligomer or polymer with carbonate segment chemical structure
    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.
