A telechelic polymer or oligomer is a prepolymer capable of entering into further polymerization or other reactions through its reactive end-groups. It can be used for example to synthesize block copolymers. By definition, a telechelic polymer is a di-end-functional polymer where both ends possess the same functionality. Where the chain-ends of the polymer are not of the same functionality they are termed di-end-functional polymers. All polymers resulting from living polymerization are end-functional but may not necessarily be telechelic.〔 To prepare polymers by step-growth polymerization, telechelic polymers like polymeric diols and epoxy prepolymers can be used. The main examples are: * Polyether diols; * Polyester diols; * Polycarbonate diols: Polyhexamethylene carbonate diol (PHMCD); * Polyalcadiene diols: Hydroxyl-terminated polybutadiene (PBHT)... Other examples of telechelic polymers are the halato-telechelic polymers or halatopolymers. The end-groups of these polymers are ionic or ionizable like carboxylate or quaternary ammonium groups. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Telechelic polymer」の詳細全文を読む スポンサード リンク
