Abstract

Glycidyl triazolyl polymer (GTP), which is the product of the Huisgen dipolar cycloaddition reaction between glycidyl azide polymer and alkyne derivatives, is featured here. GTP is the multifunctionalized poly(ethylene glycol) (PEG). The drawback of PEG is that linear PEG has the functional group only at both ends. The low loading capability of the functional groups limits the possibilities of PEG applications. GTP facilitates the synthesis of multifunctionalized PEG derivatives. In this article, 74 examples of GTP homopolymers and copolymers are introduced. The synthetic protocols and work‐up processes of GTP are summarized. In addition, application studies are reviewed: for example, stimuli‐responsive and self‐healing materials, materials for electrical memory devices, ion‐conductive materials, and biomedical materials. Finally, some issues on GTP synthesis and future directions for GTP‐based polymer materials are proposed.
