Even for the RC sample with the shortest branch chains, a plateau region was observed for the dynamic modulus G*(ω) in the middle angular frequency ω region, suggesting that intermolecular branch chain entanglement occurred. In the ω region between the plateau and terminal regions, G*(ω) was observed with a weaker ω dependence than the terminal relaxation. This behavior was more pronounced for RC samples with shorter branch chains and for the corresponding linear comb (LC) samples than for the RC ones. The molecular weight dependence of the zero-shear viscosity η0 and the steady-state recoverable compliance Jeo of the RC and LC samples was evaluated, and the effects of different backbone molecular structures (i.e., ring or linear) on the terminal relaxation behavior was discussed. Moreover, the G*(ω) data were analyzed with two models: the comb-Rouse model, in which the structures of the RC/LC molecules are taken into account by graph theory, and the Milner-McLeish model for entangled star-shaped polymers. The former model qualitatively described the terminal relaxation behavior of G*(ω) at low ω but failed to reproduce the plateau in the middle ω range. Conversely, the latter model described the entanglement plateau in the middle ω range, but the difference in the terminal relaxation regime for the RC/LC samples seen in the data and the comb-Rouse model disappeared.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Springer Nature", "subitem_publisher_language": "en"}]}, "item_9_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1038/s41428-022-00686-0", "subitem_relation_type_select": "DOI"}}]}, "item_9_source_id_7": {"attribute_name": "収録物識別子", "attribute_value_mlt": [{"subitem_source_identifier": "0032-3896", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "embargoed access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_f1cf"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Doi, Yuya", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kitamura, Jinya", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Uneyama, Takashi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Masubuchi, Yuichi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takano, Atsushi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takahashi, Yoshiaki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Matsushita, Yushu", "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": "2023-05-01"}], "displaytype": "detail", "download_preview_message": "Download / Preview is available from 2023/4/30.", "file_order": 0, "filename": "20220623-RingComb-tiff-plane.pdf", "filesize": [{"value": "3.7 MB"}], "format": "application/pdf", "future_date_message": "Download is available from 2023/4/30.", "is_thumbnail": false, "mimetype": "application/pdf", "size": 3700000.0, "url": {"objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/2004225/files/20220623-RingComb-tiff-plane.pdf"}, "version_id": "5c91a760-9343-408c-8b3b-2a090a263135"}]}, "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": "Viscoelastic properties of comb-shaped ring polystyrenes", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Viscoelastic properties of comb-shaped ring polystyrenes", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "17", "path": ["322"], "permalink_uri": "http://hdl.handle.net/2237/0002004225", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-11-29"}, "publish_date": "2022-11-29", "publish_status": "0", "recid": "2004225", "relation": {}, "relation_version_is_last": true, "title": ["Viscoelastic properties of comb-shaped ring polystyrenes"], "weko_shared_id": -1}
