However, hydraulicity has been difficult to achieve for organic materials due to the lack of a strategy for wet curing while ensuring water resistance after curing. Here, we report unprecedented hydraulicity in an organic polymer enabled by an unusual water\u2010induced polarity inversion, in which the reaction of a hydrophilic polymer with water induces hydrophobization via sol\u2013gel reaction of silatrane. A model study using a low\u2010molecular\u2010weight silatrane revealed that water drives the sol\u2013gel reaction, which is autocatalyzed by triethanolamine generated in situ. A silatrane\u2010containing polymer, prepared by conventional free\u2010radical polymerization, was obtained as a powder but rapidly plasticized upon addition of water. The formed sticky putty gradually transformed first into a soft hydrogel and finally into a rigid solid through hydrophobization associated with the formation of silsesquioxane structures. This unique behavior enabled not only wet molding into desired structures but also underwater adhesion, as demonstrated by repairing a broken vial and bonding substrates. These findings provide a versatile design strategy for organic materials exhibiting hydraulicity.<\/jats:p>","DOI":"10.1002\/anie.1794764","type":"journal-article","created":{"date-parts":[[2026,9,10]],"date-time":"2026-09-10T08:37:41Z","timestamp":1789029461000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hydraulicity in Organic Polymers Enabled by Hydrophobization Upon Water\u2010Triggered Curing of Hydrophilic Chains"],"prefix":"10.1002","author":[{"given":"Rei","family":"Tokumitsu","sequence":"first","affiliation":[{"name":"Department of Chemical Science and Engineering School of Materials and Chemical Technology Institute of Science Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shio","family":"Uebo","sequence":"additional","affiliation":[{"name":"Department of Chemical Science and Engineering School of Materials and Chemical Technology Institute of Science Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0139-8124","authenticated-orcid":false,"given":"Akira","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Chemical Science and Engineering School of Materials and Chemical Technology Institute of Science Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1512-671X","authenticated-orcid":false,"given":"Hideyuki","family":"Otsuka","sequence":"additional","affiliation":[{"name":"Department of Chemical Science and Engineering School of Materials and Chemical Technology Institute of Science Tokyo  Tokyo Japan"},{"name":"Research Center for Autonomous Systems Materialogy (AsMAT) Institute of Integrated Research Institute of Science Tokyo  Yokohama Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,10]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr100162c"},{"key":"e_1_2_6_3_1","doi-asserted-by":"crossref","first-page":"31","DOI":"10.1016\/j.cogsc.2017.03.009","article-title":"Water as Green Extraction Solvent: Principles and Reasons for Its Use","volume":"5","author":"Castro\u2010Puyana M.","year":"2017","journal-title":"Current Opinion in Green and Sustainable Chemistry"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.7b00417"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1039\/D0SC06000C"},{"key":"e_1_2_6_6_1","first-page":"123","article-title":"Building a Roman Pila in the Sea\u2014Experimental Archaeology at Brindisi","volume":"34","author":"Hohlfelder R.
