In the screening of candidate materials, it is essential to consider not only separation performance but also solubility and polymerizability during the synthesis process. Low solubility or polymerizability can inhibit membrane fabrication and the evaluation of separation performance, potentially leading to wasted resources and effort. In this study, we developed machine learning models to predict the solubility and polymerizability of polyimides. Mixture features derived from molecular descriptors of multiple monomers and mixing ratios were used as inputs for the classification models. The models were then applied to novel candidates, and their effectiveness was validated experimentally.\n                  <\/jats:p>","DOI":"10.1002\/minf.70032","type":"journal-article","created":{"date-parts":[[2026,4,22]],"date-time":"2026-04-22T13:54:45Z","timestamp":1776866085000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Machine Learning Models Predicting Solubility and Polymerizability of Polyimides Considering Multiple Monomers for CO\n                    <sub>2<\/sub>\n                    Separation Membranes"],"prefix":"10.1002","volume":"45","author":[{"given":"Yuto","family":"Shino","sequence":"first","affiliation":[{"name":"Department of Applied Chemistry School of Science and Technology Meiji University  Kawasaki Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Motosuke","family":"Katayama","sequence":"additional","affiliation":[{"name":"Nitto Denko Corporation  Ibaraki Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuri","family":"Ito","sequence":"additional","affiliation":[{"name":"Nitto Denko Corporation  Ibaraki Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8367-6476","authenticated-orcid":false,"given":"Hiromasa","family":"Kaneko","sequence":"additional","affiliation":[{"name":"Department of Applied Chemistry School of Science and Technology Meiji University  Kawasaki Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,22]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.memsci.2022.121199"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.reactfunctpolym.2017.09.002"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1295\/polymj.PJ2005257"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mtcomm.2018.01.014"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.molliq.2019.111854"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.5360\/membrane.50.206"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsami.6b12766"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1021\/ci050559o"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.iecr.5b01457"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/minf.201800150"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1001-0742(08)60018-2"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1039\/C8EN00085A"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/minf.201100129"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v036.i11"},{"key":"e_1_2_9_16_1","unstructured":"RDKit: Open\u2010source cheminformatics https:\/\/www.rdkit.org."},{"key":"e_1_2_9_17_1","unstructured":"CODESSA SemiChem Inc (http:\/\/www.semichem.com\/ codessa.html)."},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8137.1912.tb05611.x"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.2331\/suisan.22.526"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.2307\/1932409"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.1538-7305.1950.tb00463.x"},{"key":"e_1_2_9_22_1","first-page":"153","article-title":"On habitat and association in anopheline larvae in South India","volume":"3","author":"Russell P.
