The reaction of ɛ-CL and GPE proceeded efficiently in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) at 170°C for 2 h. The monomer reactivities r1 of ɛ-CL and r2 of GPE calculated according to the Fineman-Ross method and the Kelen-Tüdös method were 0.58 and 5.52, respectively. These values indicate that poly(ɛ-CL-co-GPE) has a pseudo-block gradient copolymer. Based on these results, we examined the thermal curing reactions of certain epoxy resins with ɛ-CL. The corresponding novel cured products were obtained quantitatively, and each of them showed a high glass transition temperature and high thermal stability, presumably due at least in part to a pseudo-block gradient primary structure resembling that of poly(ɛ-CL-co-GPE).","subitem_description_type":"Other"}]},"item_9_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"26884","nameIdentifierScheme":"WEKO"}],"names":[{"name":"工藤, 宏人"}]},{"nameIdentifiers":[{"nameIdentifier":"26885","nameIdentifierScheme":"WEKO"}],"names":[{"name":"歩谷, 健太郎"}]}]},"item_9_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wiley"}]},"item_9_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1002/pola.28095","subitem_relation_type_select":"DOI"}}]},"item_9_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"This is the peer reviewed version of the following article: Kudo, H. and Buya, K.
