The methyl ester with methoxymethyl (1-MOM) and allyl (1-allyl) protecting groups were polymerized by isopropyl α-lithioisobutyrate (Li-iPrIB) in toluene at −78 °C, affording highly isotactic polymers. Similarly, the polymerization of ethyl ester (2-MOM) gave an isotactic polymer, while those of t-butyl (3-MOM) and isobutyl (4-MOM) ester did not form any polymeric products. The hydrolysis of poly(2-MOM) in acidic conditions resulted in the deprotection of MOM group, although the acid also catalyzed the ester exchange between the neighboring units to form lactone units, as observed by 1H NMR analysis, IR spectroscopy and thermogravimetric analysis. A film of poly(2-MOM) exposed to HCl vapor for 2 h became insoluble in any organic solvents due to the lactonization in solid state.","subitem_description_type":"Other"}]},"item_20002_description_20":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_20002_description_22":{"attribute_name":"その他の資源識別子","attribute_value_mlt":[{"subitem_description":"Macromolecular Symposia.350(1):86-98(2015)","subitem_description_type":"Other"}]},"item_20002_full_name_16":{"attribute_name":"公開者(その他言語)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"WILEY-VCH, Verlag"}]}]},"item_20002_identifier_23":{"attribute_name":"資源識別子URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/10091/00020193"}]},"item_20002_relation_32":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1002/masy.201400028","subitem_relation_type_select":"DOI"}}]},"item_20002_rights_50":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"This is the peer reviewed version of the following article: Kohsaka, Y., Suzawa, K. and Kitayama, T.
