Xu Xi, an academician, scientist of polymer materials, member of Chinese Academy of Sciences, one of the founders of polymer materials. The professor of Sichuan university, director for polymer institute, professor in shanghai jiao tong university, director for polymer materials institute, member of the second Academic Committee in the State Key Laboratory of "Oil and Gas Reservoir Geology and Exploitation" in Southwest Petroleum University. Chief editor of “polymer materials and engineering”, and “oilfield chemistry”. The former chief editor of the polymer chemical industry branch of “encyclopedia of china •chemical”, the vice chief editor of the polymer chemical branch of” encyclopedia of china •chemical”, the chief editor of the polymer materials branch of “encyclopedia of materials science and technology”.
Professor XuXi had been engaged in the work of fields ,such as polymer chemical, the forming foundation theory of polymer materials, the high molecule force chemistry, oilfield chemistry, radiation chemistry, over a long period of time. As early as the later 1950s, he had been engaged in the study of the high molecule force chemistry. The force chemistry is the interdisciplinary of chemistry and mechanics. Generally speaking, high molecule force chemistry is mainly about the performance degradation and structure failure of polymer materials caused by stress. While he mainly study the positive effect of stress on poltmer materials. The Aamerican famous force-chemist R.S.Porter extracted XuXi’s all research results in the 1960s in his monograph “Polymer Stress Reactions”(Acadamic Press ,New York,1979). In 1980s, XuXi and his team synthesized 18 block / graft polymers, whose acquisition may be difficult from monomer, by ultrasonic effect. These polymers can be used as new high-molecular materials, such as solubilizer for the immiscible polymer, chemicals for exploration and development of oil and gas field, and metal cold working lubricant, and so on. His research results on copolymerization on degradation and graft(block) of polymer under ultrasonic effect is rated as international advanced level and obtained the second state natural science award in 1987. In his long-term research field, professor XuXi has published more than 300 papers in academic journals at home and abroad, written 4 works and translated books, obtained 28 national patents. He was awarded state natural science awards and national innovation prizes, et al, more than 20, awards belonging to state, ministry and provincial level, the national excellent teaching award in discipline construction and the cultivation of high-level talents of polymer material sciences, the progress award in science and technology by heliangheli fund, achievement award of houdebang award in chemical science and technology. He had been awarded as advanced science and technology workers in colleges and universities, model worker at national education system, advanced person in national defense and military industry cooperation.
Professor XuXi has been older than 80 but still work hardly in the front line of scientific research and teaching. He said,“though I’m old, I still think I have much to do and I have enough confidence in myself. What I’m thinking is how to work together with domestic insiders and overseas chinese to set up Chinese Nation’s international reputation and position in the field of polymer materials science.” His motto is “the fun of life is lies in selfless dedication.” His greatest aspiration is “Chinese can be universally respected by the world”.
