Chuncai Yang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • End-functionalized aniline-based oligomers, corrosion-resistant copolymers and methods of making the same
    Patent number: 6518394
    Abstract: Methods of forming low molecular weight oligomers of aniline-based compounds are provided as well as methods of forming varied molecular weight oligomers and polymers that are aniline-based which are end-functionalized and capable of being reacted with other monomeric species to form a variety of copolymers. The oligomers, end-functionalized oligomers and copolymers exhibit corrosion-resistant properties and provide corrosion-resistant compounds for use on various substrates.
    Type: Grant
    Filed: January 5, 2001
    Date of Patent: February 11, 2003
    Assignee: Drexel University
    Inventors: Yen Wei, Chuncai Yang, Tianzhong Ding, Xinru Jia, Danliang Jin, Jui-Ming Yeh, Jianguo Wang
