Optical interferometry established the complete compatibility of the components before polymerization, and the critical PPG concentration predicted as corresponding to the center of the phase inversion region (28 vol.%) was determined. SEM confirmed the formation of the predicted phase structure, characterized by interpenetrating continuous phases. FTIR spectroscopy showed that the introduction of PPG has virtually no effect on the conversion degree (92.3% for neat BPADMA and 91.5% for BPADMA\u2013PPG blend prepared by volume). The enhanced deformation capacity and reduced compressive resistance are attributed to the formed phase structure.<\/jats:p>","DOI":"10.3390\/polym18182251","type":"journal-article","created":{"date-parts":[[2026,9,15]],"date-time":"2026-09-15T18:23:53Z","timestamp":1789496633000},"page":"2251","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Photopolymerization-Induced Phase Separation in a Polypropylene Glycol-Modified Dimethacrylate System"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-6452-3971","authenticated-orcid":false,"given":"Irina D.","family":"Shapiro","sequence":"first","affiliation":[{"name":"Frumkin Institute of Physical Chemistry and Electrochemistry, Russian Academy of Sciences (IPCE RAS), 31-4, Leninsky Prospect, 119071 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3664-2027","authenticated-orcid":false,"given":"Irina O.","family":"Plyusnina","sequence":"additional","affiliation":[{"name":"Frumkin Institute of Physical Chemistry and Electrochemistry, Russian Academy of Sciences (IPCE RAS), 31-4, Leninsky Prospect, 119071 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3227-3321","authenticated-orcid":false,"given":"Nikita Yu.","family":"Budylin","sequence":"additional","affiliation":[{"name":"Frumkin Institute of Physical Chemistry and Electrochemistry, Russian Academy of Sciences (IPCE RAS), 31-4, Leninsky Prospect, 119071 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0070-3374","authenticated-orcid":false,"given":"Uliana V.","family":"Nikulova","sequence":"additional","affiliation":[{"name":"Frumkin Institute of Physical Chemistry and Electrochemistry, Russian Academy of Sciences (IPCE RAS), 31-4, Leninsky Prospect, 119071 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8866-0710","authenticated-orcid":false,"given":"Aleksey V.","family":"Shapagin","sequence":"additional","affiliation":[{"name":"Frumkin Institute of Physical Chemistry and Electrochemistry, Russian Academy of Sciences (IPCE RAS), 31-4, Leninsky Prospect, 119071 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"641","DOI":"10.1016\/j.reactfunctpolym.2013.01.012","article-title":"Preparation and Characterization of Dual Curable Adhesives Containing Epoxy and Acrylate Functionalities","volume":"73","author":"Park","year":"2013","journal-title":"React.
