In this report, we explore the capability of macromolecules to interdigitate into densely grafted molecular brush copolymers. We demonstrate that by using the tendency for stereocomplexation between poly(l-lactide) and poly(d-lactide) as a driving force complementary linear polymers and brush copolymers can form a stereocomplex. However, stereocomplex formation between complementary brush copolymers is restricted and only partially observed when the side chains are of a critical molecular weight.
在本报告中，我们探究了大分子相互交错形成密集接枝分子刷共聚物的能力。我们证明，通过利用聚（L-丙交酯）和聚（D-丙交酯）之间的立体络合倾向作为驱动力，互补线性聚合物和刷状共聚物可以形成立体络合物。然而，当侧链具有临界分子量时，互补刷状共聚物之间的立体络合物形成受到限制，只能部分观察到。
