The BG:QAm:TEG liquid monomer compositions and reference compositions (40 wt.% Bis-GMA, 40 wt.% urethane-dimethacrylate (UDMA), 20 wt.% TEGDMA (BG:UD:TEG) and 60 wt.% Bis-GMA, 40 wt.% TEGDMA (BG:TEG)) were characterized in terms of their refractive index (RI) and monomer glass transition temperature (Tgm) and then photocured. The resulting copolymers were characterized in terms of the polymer glass transition temperature (Tgp), experimental polymerization shrinkage (Se), water contact angle (WCA), water sorption (WS), and water solubility (SL). The prepared BG:QAm:TEG liquid monomer compositions had RI in the range 1.4997\u20131.5129, and Tgm in the range \u221252.22 to \u221242.12 \u00b0C. The BG:QAm:TEG copolymers had Tgp ranging from 42.21 to 50.81 \u00b0C, Se ranging from 5.08 to 6.40%, WCA ranging from 81.41 to 99.53\u00b0, WS ranging from 25.94 to 68.27 \u00b5g\/mm3, and SL ranging from 5.15 to 5.58 \u00b5g\/mm3. Almost all of the developed BG:QAm:TEGs fulfilled the requirements for dental materials (except BG:QA8:TEG and BG:QA10:TEG, whose WS values exceeded the 40 \u00b5g\/mm3 limit).<\/jats:p>","DOI":"10.3390\/ijms24021400","type":"journal-article","created":{"date-parts":[[2023,1,11]],"date-time":"2023-01-11T02:06:03Z","timestamp":1673402763000},"page":"1400","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Physicochemical Properties of Novel Copolymers of Quaternary Ammonium UDMA Analogues, Bis-GMA, and TEGDMA"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6978-2547","authenticated-orcid":false,"given":"Marta W.","family":"Chr\u00f3szcz-Por\u0119bska","sequence":"first","affiliation":[{"name":"Department of Physical Chemistry and Technology of Polymers, Faculty of Chemistry, Silesian University of Technology, Strzody 9 Str., 44-100 Gliwice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2708-1854","authenticated-orcid":false,"given":"Izabela M.","family":"Barszczewska-Rybarek","sequence":"additional","affiliation":[{"name":"Department of Physical Chemistry and Technology of Polymers, Faculty of Chemistry, Silesian University of Technology, Strzody 9 Str., 44-100 Gliwice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8282-4131","authenticated-orcid":false,"given":"Grzegorz","family":"Chladek","sequence":"additional","affiliation":[{"name":"Department of Engineering Materials and Biomaterials, Faculty of Mechanical Engineering, Silesian University of Technology, Konarskiego 18A Str., 44-100 Gliwice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"851","DOI":"10.1016\/j.dental.2018.03.014","article-title":"Antibacterial Quaternary Ammonium Compounds in Dental Materials: A Systematic Review","volume":"34","author":"Makvandi","year":"2018","journal-title":"Dent.
