In this paper, biodegradable blends based on poly(\u03b5-caprolactone) (PCL) and poly(lactic acid) (PLA) were prepared via reactive blending performed in an internal mixer. The PCL and PLA content varied in a ratio of 70\/30 and 55\/45. Reactive modification of PCL\/PLA via liquid organic peroxides (OP) including 0.5 wt.% of tert-butyl cumyl peroxide (BU), 2,5-dimethyl-2,5-di-(tert-butylperoxy)-hexane (HX), and tert-butyl peroxybenzoate (PB) is reported. The materials were characterized by rotational rheometer, atomic force microscopy (AFM), thermogravimetry (TGA), differential scanning calorimetry (DSC), tensile tests and biodegradability tests. It was found that the application of peroxides improves the miscibility between PCL and PLA resulted in enhanced mechanical properties and more uniform morphology. Moreover, it was observed that the biodegradation rate of PCL\/PLA blends reactively compatibilized was lower comparing to unmodified samples and strongly dependent on the blend ratio and peroxide structure. The presented results confirmed that reactive blending supported by organic peroxide is a promising approach for tailoring novel biodegradable polymeric systems with controllable biodegradation rates.<\/jats:p>","DOI":"10.3390\/ma14154205","type":"journal-article","created":{"date-parts":[[2021,7,28]],"date-time":"2021-07-28T05:23:48Z","timestamp":1627449828000},"page":"4205","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Morphology, Thermo-Mechanical Properties and Biodegradibility of PCL\/PLA Blends Reactively Compatibilized by Different Organic Peroxides"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0819-0158","authenticated-orcid":false,"given":"Marta","family":"Przybysz-Romatowska","sequence":"first","affiliation":[{"name":"Department of Polymer Technology, Faculty of Chemistry, Gda\u0144sk University of Technology, Gabriela Narutowicza 11\/12, 80-233 Gda\u0144sk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1451-6430","authenticated-orcid":false,"given":"Mateusz","family":"Barczewski","sequence":"additional","affiliation":[{"name":"Institute of Materials Technology, Poznan University of Technology, Piotrowo 3, 61-138 Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2748-0393","authenticated-orcid":false,"given":"Szymon","family":"Mania","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Technology and Biochemistry of Food, Faculty of Chemistry, Gabriela Narutowicza 11\/12, 80-233 Gda\u0144sk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5277-1830","authenticated-orcid":false,"given":"Agnieszka","family":"Tercjak","sequence":"additional","affiliation":[{"name":"Group \u2018Materials + Technologies\u2019 (GMT), Department of Chemical and Environmental Engineering, Faculty of Engineering, University of the Basque Country (UPV\/EHU), Pza Europa 1, 20018 Donostia-San Sebastian, Gipuzkoa, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6377-7050","authenticated-orcid":false,"given":"J\u00f3zef","family":"Haponiuk","sequence":"additional","affiliation":[{"name":"Department of Polymer Technology, Faculty of Chemistry, Gda\u0144sk University of Technology, Gabriela Narutowicza 11\/12, 80-233 Gda\u0144sk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0867-9794","authenticated-orcid":false,"given":"Krzysztof","family":"Formela","sequence":"additional","affiliation":[{"name":"Department of Polymer Technology, Faculty of Chemistry, Gda\u0144sk University of Technology, Gabriela Narutowicza 11\/12, 80-233 Gda\u0144sk, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"564","DOI":"10.3390\/ijms16010564","article-title":"Polyester-based(bio)degradable polymers as environmentally friendly materials for sustainable development","volume":"16","author":"Rydz","year":"2015","journal-title":"Int.
