Cleavable block copolymers could be cleaved into separate homopolymers under external stimuli (such as heat, light or agents).

这种聚合物在外部刺激下（如热、光、特殊试剂等）可以发生解离，从而变为两段均聚物。

Block copolymers have rich phase behavior,and in the bulk they can microphase-separate to form spheral,cylindrical,bi-continuous or layered structure.

嵌段共聚物有着丰富的相行为,在本体中会发生微相分离形成球形、柱形、双连续形和层状结构。

The micell of block copolymer conjugates releases drugs followed the rule of first order equation and had no burst effect.

键合物胶束体外释药遵从一级动力学，不存在突释现象。
