摘　　要：<正>结构规整的两亲嵌段共聚物的不寻常化学性质，已引起人们的广泛关注~[1,2]，树枝体（dendrimer）是一类架构密集、结构对称和具有多功能的新型特殊大分子。The design and synthesis of novel linear - dendritic and amphiphilic block copolyrners with a linear PAA as hydrophiphilic block and a dendritic poly (benzyl ether ) as hydrophobic block were described. The synthetic process consists of two steps, the PMA- poly (benzyl ether) dendrimers were synthesized using atom transfer radical polymerization ( ATRP) , and then the amphiphilic block copolyrners, PAA - poly ( benzyl ether) dendrimers, were obtained through hydrolysis of linear PMA block into PAA. These block copolyrners were characterized by 1H NMR, FT - IR and SEC, and exhibit well - defined architectures and low polydispersities.
