摘要：由N-(4-羥基苯基)馬來酰亞胺（HPM），α-溴代異丁酰溴和三乙胺反應(yīng)合成的單體N-[4-(2-溴代異丁酰氧基)苯基]馬來酰亞胺（BiBPMI），催化體系為五甲基二乙烯基三胺（PMDETA） 配體存在下的溴化亞銅，在四氫呋喃（THF）溶劑中于70℃下進行的原子轉(zhuǎn)移自由基聚合（ATRP），聚合得環(huán)狀聚合物聚N-[4-(2-溴代異丁酰氧基)苯基]馬來酰亞胺（PBiBPMI），再在催化體系為五甲基二乙烯基三胺（PMDETA） 配體存在下的溴化亞銅，在四氫呋喃（THF）溶劑中于70℃下經(jīng)由原子轉(zhuǎn)移自由基聚合（ATRP）接枝苯乙烯（St），得到環(huán)形梳狀聚合物（PBiBPMI-g-PS）。利用氣相色譜（GC），三檢測凝膠滲透色譜（TD-GPC）及核磁（1H-NMR）等方法對聚合反應(yīng)過程進行了跟蹤測試，并對合成的聚合物結(jié)構(gòu)進行了分析。 關(guān)鍵詞：原子轉(zhuǎn)移自由基聚合；環(huán)形梳狀聚合物；苯乙烯
Abstract：The inimer, N-[4-(2-bromo isobutyrate benzoyloxy) phenyl] maleimide(BiBPMI) is prepared by N-(4-hydroxyphenyl)maleimide(HPM),α-bromo isobutyryl bromide and triethylamine. The atom transfer radical polymerization (ATRP) of N-[4-(2-bromo isobutyrate benzoyloxy) phenyl] maleimide performed in the presence of catalytic system of cuprous bromide (CuBr) and pentamethyldiethylenetriamine (PMDETA) in Tetrahydrofuran(THF) solvent at the temperature (70℃) generates cyclic polymer, poly N-[4-(2-bromo isobutyrate benzoyloxy) phenyl]maleimide(PBiBPMI). Then it graft with Styrene(St) in the presence of catalytic system of cuprous bromide (CuBr) and pentamethyldiethylenetriamine (PMDETA) in Tetrahydrofuran(THF) solvent at the temperature (70℃).At last, it generates cyclic brush-like polymer(PBiBPMI-g-PS). The process of ATRP reaction was characterized by gas chromatography (GC), gel permeation chromatography (GPC), nuclear magnetic resonance (1H-NMR) and the resulting polymers was analyzed. Key words: atom transfer radical polymerization (ATRP); cyclic brush-like polymer; styrene
