China's new copolymerization catalyst has won the U.S. patent

May 10, 2005

some expert members of Shandong Branch of the Academy of materials participated in the activity. Guangzhou Chemical Co., Ltd. of the Chinese Academy of Sciences "the fixture for fixing carbon dioxide to synthesize aliphatic polycarbonate is the carrier catalyst for the combination of these structures" was recently authorized by the U.S. patent office

it is reported that the catalyst is used to catalyze the copolymerization of epoxide and carbon dioxide to synthesize polyalkane carbonate, and can be widely used in the fields of low-temperature oxygen isolating films, biodegradable plastics, elastomers, adhesives, coatings, etc. The synthesis of this kind of polymer can not only effectively utilize the greenhouse gas carbon dioxide, which is largely abandoned in industry and causes great harm to the environment, but also the product has biodegradability and will not bring the operation steps of rubber fatigue testing machine with white pollution caused by ordinary plastics. Therefore, it has a broad market prospect

considering the broad market prospect of this technology and the urgency of intellectual property protection, Guangzhou Chemical Co., Ltd. of the Chinese Academy of Sciences, after applying for a patent in China, filed a patent application with the U.S. Patent Office in 2002. After three years of efforts, it was finally successful. The acquisition of U.S. patent rights paved the way for the technology to enter the international market
