Title: Innovations of Xiyu Ke in Sulfur-Containing Polymers
Introduction
Xiyu Ke is a notable inventor based in Singapore, recognized for his contributions to the field of polymer chemistry. He has developed innovative methods for creating sulfur-containing polymers, which have significant applications in various industries, including therapeutics.
Latest Patents
Xiyu Ke holds five patents, with his latest innovations focusing on the method of making sulfur-containing polymers from hexahydrotriazine and dithiol precursors. These polythioaminal polymers are synthesized by blending hexahydrotriazine precursors with dithiol precursors and subjecting them to mild heating. The resulting polymers possess a general structure where each R is independently an organic or hetero-organic group, and each R is a substituent with a molecular weight of no more than about 120 Daltons. The polymers feature sulfur-bonded species, with at least one of the species not being hydrogen. The reactive thiol groups in the polythioaminal can be utilized to attach thiol-reactive end-capping species. By employing water-soluble or water-degradable dithiols, such as polyether dithiols, water-soluble polythioaminals can be produced. These polymers may serve as carriers for active agents, delivering therapeutics with non-toxic aqueous degradation products.
Career Highlights
Throughout his career, Xiyu Ke has worked with prominent organizations, including IBM and the Agency for Science, Technology and Research. His experience in these institutions has contributed to his expertise in polymer science and innovation.
Collaborations
Xiyu Ke has collaborated with notable colleagues, including James L. Hedrick and Yi Yan Yang, enhancing his research and development efforts in the field of polymer chemistry.
Conclusion
Xiyu Ke's innovative work in sulfur-containing polymers showcases his significant contributions to the field of chemistry. His patents and collaborations reflect his commitment to advancing technology and improving therapeutic delivery systems.
