In the absence of the syndiotactic-specificity inducers, the syndiotacticities of the obtained polymers gradually increased as the bulkiness of the N-substituents increased.  Both HMPA and 3Me3PenOH induced the syndiotactic-specificities in the NNPAAm polymerizations as well as in the NIPAAm polymerizations.  The addition of 3Me3PenOH into the polymerizations of NMAAm significantly induced the syndiotactic-specificities, whereas the tacticities of the obtained polymers were hardly affected by adding HMPA.  In the polymerizations of bulkier monomers, such as NBnAAm and NPhEAAm, HMPA worked as the syndiotactic-specificity inducer at higher temperatures, whereas 3Me3PenOH hardly influenced the stereospecificity, regardless of the temperatures.  The phase transition behaviors of the aqueous solutions of poly(NNPAAm)s were also investigated.  It appeared that the poly(NNPAAm) with racemo dyad content of 70% exhibited unusual large hysteresis between the heating and cooling processes.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wiley","subitem_publisher_language":"en"}]},"item_10001_rights_15":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"This is the peer reviewed version of the following article: Hirano, T., Nakamura, K., Kamikubo, T., Ishii, S., Tani, K., Mori, T. and Sato, T.
