以甲基-溴异丁酸甲酯（MBiB）、溴化铜（cur）、溴化铜（II）、溴化铜（cur(2)）和1,1,4,7,10,10-六亚甲基三乙基四胺（HMTETA）为原料，采用原子转移自由基聚合（ATRP）方法，在60℃的甲苯中聚合1-甲基丙烯酸金刚酯（AdMA），制得性质明确的聚（1-甲基丙烯酸金刚酯）（PAdMA）。同时控制分子量和立构规整度的莲花成功通过ATRP方法使用MBiB CuBr / CuBr /(2)三(2 -(二甲胺基)乙基]amine-initiating系统1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) -20度c块共聚AdMA和甲基丙烯酸甲酯(MMA)成功地实现了聚(甲基丙烯酸甲酯)macroinitiator / CuBr (2) / HMTETA /锡(2)基于活化剂2-ethylhexanoate-initiating系统生成的电子转移（AGET） ATRP方法。差示扫描量热法揭示了所得PAdMA的玻璃化转变温度、分子量和弹性之间的关系。高分子学报（2010）42,626-631；doi: 10.1038 / pj.2010.55;2010年6月30日在线发布
1-Adamantyl methacrylate (AdMA) was polymerized using the atom transfer radical polymerization (ATRP) method with methyl alpha-bromoisobutyrate (MBiB), copper(I) bromide (CuBr), copper(II) bromide (CuBr(2)) and 1,1,4,7,10,10-hexamethyltriethylenetetramine (HMTETA) in toluene at 60 degrees C, producing well-defined poly(1-adamantyl methacrylate) (PAdMA). Simultaneous control of the molecular weight and tacticity of PAdMA was successfully achieved by the ATRP method using the MBiB/CuBr/CuBr(2)/ tris[2-(dimethylamino)ethyl]amine-initiating system in 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) at -20 degrees C. Block copolymerization of AdMA and methyl methacrylate (MMA) was successfully achieved by the poly(methyl methacrylate) macroinitiator/CuBr(2)/HMTETA/tin(II) 2-ethylhexanoate-initiating system based on activators generated by electron transfer (AGET) ATRP method. Differential scanning calorimetry revealed the relationship between the glass transition temperature, molecular weight and tacticity of the obtained PAdMA.
