  • Patent number: 11807716
    Abstract: An oligomer (2,6-dimethylphenylene ether) is provided. Its structure is shown as follows: which comprises separately independent hydrogen; alkyl or phenyl; separately independent —NR—, —CO—, —SO—, —CS—, —SO2—, —CH2—, —O—, null, —C(CH3)2—, or and a hydrogen, The features of the cured products include a high glass-transition temperature, a low dielectric feature, preferred thermal stability, and good flame retardancy. The present invention effectively controls the number-average molecular weight of the product to obtain excellent organic solubility.
    Type: Grant

    Date of Patent: November 7, 2023
    Assignee: CPC Corporation, Taiwan
    Inventors: Sheng-De Li, Ching-Hsuan Lin, Yi-Hsuan Hsieh, Wei-Yen Chen, Way-Chih Hsu, Jui-Fu Kao, Ming-Yu Huang, Jann-Chen Lin, Yih-Ping Wang
  • Patent number: 11787904
    Abstract: A phosphinated (2,6-dimethylphenyl ether) oligomer, preparation method thereof and cured product. The phosphinated (2,6-dimethylphenyl ether) oligomer includes a structure represented by Formula (1): wherein X is a single bond, —CH2—, —O—, —C(CH3)2— or R?0, R0, R1, R2 and R3 are independently hydrogen, C1-C6 alkyl or phenyl; n and m are independently an integer from 0 to 300; p and q are independently an integer from 1 to 4; Y is hydrogen, U and V are independently an aliphatic structure.

  • Publication number: 20210403620
    Abstract: The invention discloses functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers containing dicyclopentadiene, a method of producing the same and use thereof. The cured products of the functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers of the invention exhibit low dielectric constant, low dissipation, and high glass transition temperature. As the functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers of the invention have number-average molecular weight ranging from 2500 to 6000 g/mol, the substrate made of theses functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers can pass the pressure cook test. Besides, the low dissipation factor characteristic the functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers of the invention can only be demonstrated at number-average molecular weight higher than 2500 g/mol.
