The copolymerization of N-(2,6-diethylphenyl)maleimide (2,6-DEPhMI) with IB in benzene proceeded readily in a homogeneous system to give an alternating copolymer over a wide range of the comonomer compositions in the feed. Whereas the alternating tendency of the copolymerization of other RPhMI with IB decreased depending on the alkyl substituents of RPhMI in the following order : 2,6-DEPhMI > N-(2,6-dimethylphenyl)maleimide ≥ N-(2-methylphenyl)maleimide >N-(4-ethylphenyl)maleimide. The copolymerization reactivities were discussed based on the rate constants for the homo-propagations and cross-propagations. Subsequently, the effect of the solvent on the rate and the reactivity ratios was examined. It was revealed that the copolymerization in chloroform proceeded with higher alternating tendency at a higher copolymerization rate than in the copolymerizations in benzene or dioxane. The copolymers of RPhMI with IB showed excellent thermal stability, i.e., high glass transition temperature and initial decomposition temperature over 200 and 350°C, respectively."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382262944405071108","@type":"Researcher","foaf:name":[{"@value":"Toru Doi"}]},{"@id":"https://cir.nii.ac.jp/crid/1382262944405071106","@type":"Researcher","foaf:name":[{"@value":"Akira Akimoto"}]},{"@id":"https://cir.nii.ac.jp/crid/1382262944405071107","@type":"Researcher","foaf:name":[{"@value":"Akikazu Matsumoto"}]},{"@id":"https://cir.nii.ac.jp/crid/1382262944405071104","@type":"Researcher","foaf:name":[{"@value":"Yoshitaka Oki"}]},{"@id":"https://cir.nii.ac.jp/crid/1382262944405071105","@type":"Researcher","foaf:name":[{"@value":"Takayuki Otsu"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"0887624X"},{"@type":"EISSN","@value":"10990518"}],"prism:publicationName":[{"@value":"Journal of Polymer Science Part A: Polymer Chemistry"}],"dc:publisher":[{"@value":"Wiley"}],"prism:publicationDate":"1996-09-15","prism:volume":"34","prism:number":"12","prism:startingPage":"2499","prism:endingPage":"2505"},"reviewed":"false","dc:rights":["http://doi.wiley.com/10.1002/tdm_license_1.1"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2F(SICI)1099-0518(19960915)34:12%3C2499::AID-POLA23%3E3.0.CO;2-2"},{"@id":"https://onlinelibrary.wiley.com/doi/full/10.1002/(SICI)1099-0518(19960915)34:12%3C2499::AID-POLA23%3E3.0.CO;2-2"}],"createdAt":"2003-07-03","modifiedAt":"2021-07-01","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004239513589120","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"The First Synthesis of Periodic and Alternating Glycopolymers by RAFT Polymerization: A Novel Synthetic Pathway for Glycosaminoglycan Mimics"}]},{"@id":"https://cir.nii.ac.jp/crid/1360283689587789952","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Penultimate Unit and Solvent Effects on 2:1 Sequence Control During Radical Copolymerization of <i>N</i>‐Phenylmaleimide With <i>β</i>‐Pinene"}]},{"@id":"https://cir.nii.ac.jp/crid/1390305898131158656","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"マレイミド共重合体のエステル交換反応とチオール・エン反応による耐熱透明ポリマー材料の合成"},{"@language":"en","@value":"Synthesis of Heat-Resistant Transparent Polymer Materials by Transesterification and Thiol-Ene Reactions of Maleimide Copolymers"},{"@language":"ja-Kana","@value":"マレイミド キョウ ジュウゴウタイ ノ エステル コウカン ハンノウ ト チオール ・ エン ハンノウ ニ ヨル タイネツ トウメイ ポリマー ザイリョウ ノ ゴウセイ"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1002/(sici)1099-0518(19960915)34:12<2499::aid-pola23>3.0.co;2-2"},{"@type":"OPENAIRE","@value":"doi_dedup___::a8e6fe6c396f6de2a147ab4f92d18ff1"},{"@type":"CROSSREF","@value":"10.3390/polym11010070_references_DOI_92lbMMJBmmNkduSWoyBQSfooS9V"},{"@type":"CROSSREF","@value":"10.1002/macp.201200421_references_DOI_92lbMMJBmmNkduSWoyBQSfooS9V"},{"@type":"CROSSREF","@value":"10.11618/adhesion.59.329_references_DOI_92lbMMJBmmNkduSWoyBQSfooS9V"}]}
