| 摘 要： | 以Mn_2(CO)_(10)—CBr_4为引发剂,在AlEt_(1.5) Cl_(1.5)存在下,合成了交替共聚物的嵌段聚合物,Poly(St-a-MA)-b-(IP-a-MMA)-b-(St-a-MA)]。NMR研究表明该嵌段聚合物各段都具有交替结构。扭辫法测定动态力学性能显示有两个T_g,分别为38℃和75℃。透射电镜研究表明,该聚合物具有两相结构。微区随硬段分子量增大而增大。

| Abstract: | Block polymer of alternating copolymers, poly (St-a-MA)-b- (IP-a-MMA) -b- (St-a-MA)] (I), has been synthesized in the presence of AlEt1.5Cl1.5 by using Mn2(CO)10-CBr4 initiation system. The GPC results indicated that there is no unreacted prepolymer in I purified by precipitation.The study of NMR showed that every block of polymer I has alternating structure. The dynamic mechanical properties of I measured by torsional braid method indicated that the polymer has two Tg, being 38℃ and 75℃, respectively. The transmission electron micrographs of I showed they have two phase structure and the domain size indreases with increasing molecular weight of hard black. |
