Methacrylic polymer having a terminal functional group and composition thereof |
摘要 |
The present invention provides a polymer obtained by polymerizing a mixture composed of a methacrylic ester monomer having an electron-donating group bonded to a specific site of its ester-forming residue (its alcohol moiety) and optionally a lactone or lactide, while using an alkali metal alcoholate as a polymerization initiator. Moreover, it also provides a process for preparing the polymer and polymer micelles formed from the polymer. Since the polymer has a functional group corresponding to the polymerization initiator and the aforesaid electron-donating groups (functional groups), it can perform a great variety of functions by taking advantage of these functional groups.
