介绍了新型树枝状-线型嵌段共聚物的设计与合成。以树枝状聚芳醚2-溴异丁酸酯为大分子引发剂，采用原子转移自由基聚合法合成了共聚物。以CuBr/bipy为催化剂，在120℃下进行了本体ATRP，得到了多分散性小于1.36的嵌段共聚物。
The design and synthesis of novel dendritic-linear block copolymers were described. The copolymers were synthesized by atom transfer radical polymerization (ATRP) using dendritic polyarylether 2-bromoisobutyrate macroinitiator. ATRP carried out in bulk with CuBr/bipy catalyst at 120℃,yielded well-defined block copolymers with polydispersities less than 1.36.
