| Outline of Final Research Achievements |
We have established that polymerization of diazoacetates with sterically bulky substituents such as dendron and phosphazene proceeds in a living manner, affording polymers with narrow molecular weight distribution and block copolymers with a well-defined structure. A new initiating system, (naphthoquinone)Pd/borate, was revealed to be effective for controlling the polymerization of non-bulky ethyl diazoacetate.
In order to establish a method for characterizing tacticty of poly(alkoxycarbonylmethylene)s by NMR, tetramer of methyl diazoacetate was prepared and its diastereomeric separation into four isomers was successfully conducted. Two types of new initiating systems for diazoacetates were found to afford polymers with relatively controlled stereostructures.
