Precipitation polymerization was completed within 2 min. The molecular weight of the resulting polymer (27.7 x 103; dispersity of 1.78) was comparable to that of polymers obtained by typical polymerization at 70 degrees C and significantly exceeding those of polymers obtained by polymerization in high-temperature organic solvents. This implies that the main factor governing the polymerization rate is a kinetic effect due to hydrogen bonding between the carbonyl groups and water molecules; under these conditions, disproportionation termination was suppressed. The polymerization process developed herein using high-temperature water offers the benefits of a short reaction time and a low environmental impact, thus holding great promise for industrial applications.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Industrial & Engineering Chemistry Research 61(46) : 17012-17016(2022)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"髙坂, 泰弘","subitem_link_url":"https://soar-rd.shinshu-u.ac.jp/profile/ja.WNTUPVca.html"},{"subitem_link_text":"長田, 光正","subitem_link_url":"https://soar-rd.shinshu-u.ac.jp/profile/ja.WmLUZFTp.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ACS"}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1021/acs.iecr.2c02831"}],"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1021/acs.iecr.2c02831","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0888-5885","subitem_source_identifier_type":"EISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ishii, Sumito","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Sezai, Akinori","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Kohsaka, Yasuhiro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Deguchi, Shigeru","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Osada, Mitsumasa","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-11-10"}],"filename":"IECH61-17012.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://soar-ir.repo.nii.ac.jp/record/2001259/files/IECH61-17012.pdf"},"version_id":"97a5d79e-4bf8-4d67-a7c6-6136477a5b9f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Environment-friendly polymerization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Radical polymerization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"High production rate","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Molecular weight","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Dispersity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Solvent-free","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Recombination","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"High-Speed Synthesis of Thermo-responsive Polymers by Boosted Polymerization of N,N-Diethyl Acrylamide in High-Temperature Water","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High-Speed Synthesis of Thermo-responsive Polymers by Boosted Polymerization of N,N-Diethyl Acrylamide in High-Temperature Water","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["1310"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-12-15"},"publish_date":"2022-12-15","publish_status":"0","recid":"2001259","relation_version_is_last":true,"title":["High-Speed Synthesis of Thermo-responsive Polymers by Boosted Polymerization of N,N-Diethyl Acrylamide in High-Temperature Water"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-15T05:13:58.864988+00:00"}
