采用浸渍法制备了不同含量MgO改性的γ-Al2O3，采用X射线衍射、N2物理吸附、NH3的程序升温脱附和程序升温还原等手段表征了催化剂的结构、表面酸性和氧化还原性质，并对CuCl2-KCl/MgO-Al2O3催化剂催化乙烷氧氯化制氯乙烯反应进行了活性评价。

Conductivity of Polyoxyethylene/Poly (2-vinyl pyridine)Blend and Compatibilizing Effect of Lithium Perchlorate;2. Graft terpolymerization of polyoxyethylene macromer with acrylates;3. Then multiblock copolymers was obtained by condensing polyoxyethylene and poly(2 vinylpyridine)with dichloromethane in the presence of potassium hydroxide.

甲基萘锂作为引发剂利用阴离子聚合得到 2 乙烯基吡啶的遥爪双羟基低聚物(P2VP)，然后以二氯甲烷作偶联剂与聚环氧乙烷反应制备P2VP和PEO多嵌段共聚物，考察了反应时间对偶联反应的影响，并对共聚物进行了IR和1H NMR表征，由1H NMR谱的积分曲线得到了共聚物中PEO链段质量分数。

The diblock copolymer of styrene and chloromethyl-4-vinyl-benzene was obtained by means of reverse addition fragmentation chain transfer reaction living free radical polymerization. The chloromethyl groups in PS-bPCVB were transformed into azidomethyl groups, and then into 1,2,3-triazol groups via click chemistry. The diblobk copolymer containing 1,2,3-triazol groups was thus obtained. The results from NMR spectra suggested a complete transformation from chloromethyl groups to triazol groups.

通过RAFT活自由基聚合方法制备聚（苯乙烯-b-对氯亚甲基苯乙烯）二嵌段共聚物，其中的氯亚甲基侧基经叠氮化反应后与丙炔醇进行点击反应，最终获得了含有1，2，3-三氮唑官能团的聚苯乙烯二嵌段共聚物，核磁共振谱表征结果证明，PS-b-PCVB中的氯亚甲基完全转变成了1，2，3-三氮唑基团。
