Title: METHOD FOR PRODUCING POLYMER HAVING AMINO GROUP AT END
Abstract:
The purpose of the present invention is to provide a method for producing a polymer having an amino group at the end with which it is possible to obtain a polymer having an amino group at the end at a high conversion rate even by a relatively short reaction time. This method for producing a polymer having an amino group at the end has a step (C) that reacts a polymer having an azide group at the end of the polymer chain, obtained by living cationic polymerization, and a tri-substituted phosphine, and obtains a polymer having an iminophosphorane group at the end. In this production method, the polymer having an azide group at the end of the polymer chain is preferably obtained by a step (A) that subjects a monomer to living cationic polymerization and a step (B) that stops the living cationic polymerization using an azidation reagent and obtains a polymer having an azide group at the end of the polymer chain.
