The AB2 monomers bear two azide functionalities and one alkyne functionality, which have been installed onto a 1,3,5 trisubstituted benzene aromatic skeleton. This synthesis has been optimized in terms of its purification strategies, with an eye on its scalability for the potential industrial applications of hyperbranched polymers as viscosity modifiers. By taking advantage of the modularity of the synthesis, we have been able to install short polylactic acid fragments as the spacing units between the complementary reactive azide and alkyne functionalities, aiming to introduce elements of biodegradability into the final products. The hyperbranched polymers have been obtained with good molecular weights and degrees of polymerization and branching, testifying to the effectiveness of the synthetic design. Simple experiments on glass surfaces have highlighted the possibility of conducting the polymerizations and the formation of the hyperbranched polymers directly in thin films at room temperature.<\/jats:p>","DOI":"10.3390\/ijms24087620","type":"journal-article","created":{"date-parts":[[2023,4,21]],"date-time":"2023-04-21T03:01:48Z","timestamp":1682046108000},"page":"7620","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Polylactic-Containing Hyperbranched Polymers through the CuAAC Polymerization of Aromatic AB2 Monomers"],"prefix":"10.3390","volume":"24","author":[{"given":"Aurora","family":"Pacini","sequence":"first","affiliation":[{"name":"Department of Chemistry, INSTM Research Unit, University of Pavia, Viale Taramelli 10, 27100 Pavia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7232-5707","authenticated-orcid":false,"given":"Andrea","family":"Nitti","sequence":"additional","affiliation":[{"name":"Department of Chemistry, INSTM Research Unit, University of Pavia, Viale Taramelli 10, 27100 Pavia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcello","family":"Vitale","sequence":"additional","affiliation":[{"name":"IVM Chemicals s.r.l., Viale della Stazione 3, 27020 Parona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8273-3798","authenticated-orcid":false,"given":"Dario","family":"Pasini","sequence":"additional","affiliation":[{"name":"Department of Chemistry, INSTM Research Unit, University of Pavia, Viale Taramelli 10, 27100 Pavia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5924","DOI":"10.1021\/cr900068q","article-title":"Hyperbranched and Highly Branched Polymer Architectures\u2014Synthetic Strategies and Major Characterization Aspects","volume":"109","author":"Voit","year":"2009","journal-title":"Chem.
