The crystal structure at room temperature was found to be the so-called α form with the all- trans  zigzag methylene segments. When the samples were heated, the infrared progression bands of the methylene segments, which are sensitive to the length of all- trans  segmental parts, were found to change their spectral patterns in the transition temperature region: the progression bands decreased in intensity and disappeared above the transition region. At the same time several new bands were observed to appear, which were found to correspond to the progression bands of (CH 2 ) 7 –(CH 2 ) 5   trans -zigzag segments. These spectral changes indicate that the methylene segments were conformationally disordered by an invasion of some  gauche  bonds and as a result the effective length of  trans -zigzag segments became shorter. This conformational disordering was found to occur more remarkably in the methylene segment of NH–(CH 2 ) 10 –NH part than the CO–(CH 2 ) 8 –CO part. At the same time the infrared bands of amide groups, in particular the bands sensitive to the twisting angles about the CH 2 –amide bonds were found to show the remarkable change, indicating the local conformational change from planar-zigzag to twisted form in the CH 2 –amide moiety. The frequency shift of amide A band (NH stretching mode) indicated a weakening of intermolecular hydrogen bonds, which however, did not disappear up to the melting region. From these data combined with the X-ray diffraction data, the structural disordering in the Brill transition phenomena was deduced concretely."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670320166686720","@type":"Researcher","foaf:name":[{"@value":"Yayoi Yoshioka"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320166686721","@type":"Researcher","foaf:name":[{"@value":"Kohji Tashiro"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00323861"}],"prism:publicationName":[{"@value":"Polymer"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"2003-10","prism:volume":"44","prism:number":"22","prism:startingPage":"7007","prism:endingPage":"7019"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S0032386103007948?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:S0032386103007948?httpAccept=text/plain"}],"createdAt":"2003-09-22","modifiedAt":"2019-02-23","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004233456390528","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Phase-transition behavior of a crystalline polymer near the melting point: case studies of the ferroelectric phase transition of poly(vinylidene fluoride) and the β-to-α transition of trans-1,4-polyisoprene"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285707430001408","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Crystal structure analyses of arylate polyesters with long methylene segments and their model compounds on the basis of 2-D X-ray diffractions and infrared progression bands"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567182406722688","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Crystal structure of an aliphatic polyoxamide containing methyl side-groups: Poly(2-methyl-1,8-octamethyleneoxamide)"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567182406776704","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Polymorphism of poly(nonamethyleneoxamide) crystal"}]},{"@id":"https://cir.nii.ac.jp/crid/1360846641608761856","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Polymorphism and Phase Transitions of Precisely Halogen-Substituted Polyethylene.
