专利号:US-8940855-B2 优先权日:2009-06-02 标题:Polymers bearing pendant pentafluorophenyl ester groups, and methods of synthesis and functionalization thereof 发明人:HEDRICK JAMES L; NELSON ALSHAKIM; SANDERS DANIEL P 权利人:IBM 摘要:A one pot method of preparing cyclic carbonyl compounds comprising an active pendant pentafluorophenyl ester group is disclosed. The cyclic carbonyl compounds can be polymerized by ring opening methods to form ROP polymers comprising repeat units comprising a side chain pentafluorophenyl ester group. Using a suitable nucleophile, the pendant pentafluorophenyl ester group can be selectively transformed into a variety of other functional groups before or after the ring opening polymerization.
