Nuclear magnetic resonance (RMN) and gel permeation chromatography (GPC) confirmed the diblock structure of the sulfonated copolymers. The poly(2-acryloamido-2-methylpropanesulfonic acid)-b-poly(methyl methacrylate) (PAMPS-b-PMMA) and poly(2-acryloamido-2-methylpropanesulfonic acid)-b-poly(2-hydroxyethylmethacrylate) (PAMPS-b-PHEMA) copolymers obtained are highly soluble in organic solvents and present good film-forming ability. The ion exchange capacity (IEC) of the copolymer membranes is reported. PAMPS-b-PHEMA presents the highest IEC value (3.35 mmol H+\/g), but previous crosslinking of the membrane was necessary to prevent it from dissolving in aqueous solution. PAMPS-b-PMMA exhibited IEC values in the range of 0.58\u20131.21 mmol H+\/g and it was soluble in methanol and dichloromethane and insoluble in water. These results are well correlated with both the increase in molar composition of PAMPS and the second block included in the copolymer. Thus, the proper combination of PAMPS block copolymer with hydrophilic or hydrophobic monomers will allow fine-tuning of the physical properties of the materials and may lead to many potential applications, such as polyelectrolyte membrane fuel cells or catalytic membranes for biodiesel production.<\/jats:p>","DOI":"10.3390\/polym12081663","type":"journal-article","created":{"date-parts":[[2020,7,27]],"date-time":"2020-07-27T09:24:49Z","timestamp":1595841889000},"page":"1663","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Synthesis of Poly(2-Acrylamido-2-Methylpropane Sulfonic Acid) and its Block Copolymers with Methyl Methacrylate and 2-Hydroxyethyl Methacrylate by Quasiliving Radical Polymerization Catalyzed by a Cyclometalated Ruthenium(II) Complex"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8265-0143","authenticated-orcid":false,"given":"Vanessa","family":"Mart\u00ednez-Cornejo","sequence":"first","affiliation":[{"name":"Unidad de Materiales, Centro de Investigaci\u00f3n Cient\u00edfica de Yucat\u00e1n, A.C., Calle 43 No. 130, Chuburn\u00e1 de Hidalgo, C.P. 97205 M\u00e9rida, Yucat\u00e1n, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joaquin","family":"Vel\u00e1zquez-Roblero","sequence":"additional","affiliation":[{"name":"Unidad de Materiales, Centro de Investigaci\u00f3n Cient\u00edfica de Yucat\u00e1n, A.C., Calle 43 No. 130, Chuburn\u00e1 de Hidalgo, C.P. 97205 M\u00e9rida, Yucat\u00e1n, Mexico"},{"name":"Facultad de Ingenier\u00eda Qu\u00edmica, Universidad Aut\u00f3noma de Yucat\u00e1n, Perif\u00e9rico Norte Km. 33.5, Chuburn\u00e1 de Hidalgo Inn, C.P. 97203 M\u00e9rida, Yucat\u00e1n, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronica","family":"Rosiles-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Unidad de Materiales, Centro de Investigaci\u00f3n Cient\u00edfica de Yucat\u00e1n, A.C., Calle 43 No. 130, Chuburn\u00e1 de Hidalgo, C.P. 97205 M\u00e9rida, Yucat\u00e1n, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monica","family":"Correa-Duran","sequence":"additional","affiliation":[{"name":"Unidad de Materiales, Centro de Investigaci\u00f3n Cient\u00edfica de Yucat\u00e1n, A.C., Calle 43 No. 130, Chuburn\u00e1 de Hidalgo, C.P. 97205 M\u00e9rida, Yucat\u00e1n, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9719-5996","authenticated-orcid":false,"given":"Alejandro","family":"Avila-Ortega","sequence":"additional","affiliation":[{"name":"Facultad de Ingenier\u00eda Qu\u00edmica, Universidad Aut\u00f3noma de Yucat\u00e1n, Perif\u00e9rico Norte Km. 33.5, Chuburn\u00e1 de Hidalgo Inn, C.P. 97203 M\u00e9rida, Yucat\u00e1n, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7467-7538","authenticated-orcid":false,"given":"Emanuel","family":"Hern\u00e1ndez-N\u00fa\u00f1ez","sequence":"additional","affiliation":[{"name":"CONACYT, Departamento de Recursos del Mar, Centro de Investigaci\u00f3n y de Estudios Avanzados del IPN, 97310 Unidad M\u00e9rida, Yucat\u00e1n, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5679-2081","authenticated-orcid":false,"given":"Ronan","family":"Le Lagadec","sequence":"additional","affiliation":[{"name":"Instituto de Qu\u00edmica, Universidad Nacional Aut\u00f3noma de M\u00e9xico, Circuito Exterior s\/n, Ciudad Universitaria, 04510 Ciudad de M\u00e9xico, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Ortencia","family":"Gonz\u00e1lez-D\u00edaz","sequence":"additional","affiliation":[{"name":"CONACYT\u2013Centro de Investigaci\u00f3n Cient\u00edfica de Yucat\u00e1n, A.C., Calle 43 No. 130, Chuburn\u00e1 de Hidalgo, 97205 M\u00e9rida, Yucat\u00e1n, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1035","DOI":"10.1016\/j.cej.2015.09.048","article-title":"Preparation, Characterization and Properties of PVDF-g PAMPS\/PMMA-Co-PAMPS\/Silica Nanoparticle as a New Proton Exchange Nanocomposite Membrane","volume":"284","author":"Kheirmand","year":"2016","journal-title":"Chem.
