From the examination of the solubility, the composition, the infrared spectra, and the partial thermal decomposition of the resultant polymer, it was found that copolymerization with acetaldehyde yielded a random copolymer, while copolymerization with <I>n</I>-butyraldehyde produced the copolymer having block units. The facts were also supported by the determination of the apparent values of monomer reactivity ratios. The thermal stability of the copolymers was fairly good in comparison with the homopolymers of conventional higher aliphatic aldehydes."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410001206292000256","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000283201158"}],"foaf:name":[{"@language":"en","@value":"Yamamoto Noboru"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Government Industrial Research Institute, Osaka"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001206292000257","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000283201159"}],"foaf:name":[{"@language":"en","@value":"Yamashita Iwao"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Government Industrial Research Institute, Osaka"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00323896"},{"@type":"EISSN","@value":"13490540"}],"prism:publicationName":[{"@language":"en","@value":"Polymer Journal"},{"@language":"en","@value":"Polym.
