In this article, we report the first example of radical polymerization of α-functionalized N,N-disubstituted acrylamide affording thermo-responsive hydrophilic polymers. N,N-dimethyl-α-(hydroxymethyl)acrylamide (DMαHAA) was (co)polymerized with N,N-diethylacrylamide (DEAA). Although the homopolymerization did not afford a polymeric product, the copolymerizations with various feed ratios yielded a series of the copolymers containing 0%–65% of DMαHAA units. The obtained copolymers exhibited a lower critical solution temperature (LCST) in water; the cloud points (Tcs) were linearly elevated as the contents of DMαHAA units from 32 to 64 °C, indicating that DMαHAA functioned as a more hydrophilic monomer than DEAA. The linear relationship between Tc and DMαHAA content suggests that the homopolymer, poly(DMαHAA), should have Tc at ca. 80 °C, although it is not available by direct radical homopolymerization.","subitem_description_type":"Other"}]},"item_20002_description_20":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_20002_description_22":{"attribute_name":"その他の資源識別子","attribute_value_mlt":[{"subitem_description":"Polymers.8(10):(2016)","subitem_description_type":"Other"}]},"item_20002_full_name_16":{"attribute_name":"公開者(その他言語)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"MDPI"}]}]},"item_20002_identifier_23":{"attribute_name":"資源識別子URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/10091/00020191"}]},"item_20002_relation_32":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3390/polym8100374","subitem_relation_type_select":"DOI"}}]},"item_20002_rights_50":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2016 by the authors; licensee MDPI, Basel, Switzerland.
