The process of the present invention is directed toward conducting highly selective, high yield post polymerization reactions on polymers to prepare functionalized polymers. An embodiment of the present invention comprises conducting click chemistry reactions on polymers. Preferably, the polymers were prepared by controlled polymerization processes. Therefore, embodiments of the present invention comprise processes for the preparation of polymers comprising conducting a click chemistry reaction on a functional group attached to a polymer, wherein the polymer has a molecular weight distribution of less than 2.0. The functional polymers may be prepared by converting an attached functional unit on the polymer thereby providing site specific functional materials, site specific functional materials comprising additional functionality, or chain extended functional materials. Embodiments of the process of the present invention include functionalization reactions, chain extensions reactions, to form mock copolymer linking reactions, and attaching side chains to form graft copolymers, for example.
本发明的过程旨在对聚合物进行高选择性,高产率的后聚合反应,以制备功能化聚合物。本发明的一种实施例包括在聚合物上进行点击化学反应。最好的情况是,这些聚合物是通过受控聚合过程制备的。因此,本发明的实施例包括制备聚合物的过程,其中包括在连接到聚合物的功能基团上进行点击化学反应,其中聚合物的分子量分布小于2.0。可以通过转化聚合物上的连接功能单元来制备功能性聚合物,从而提供定位特异性的功能材料,包括具有附加功能的定位特异性功能材料,或链延长的功能材料。本发明的过程实施例包括功能化反应,链延伸反应,形成模拟共聚物连接反应,以及连接侧链以形成接枝共聚物等。
