Accordingly, an exhaustive control of composition and evolution in these additives over time is necessary to validate their performance and safety during their shelf life and, consequently, their ultimate applications. Gas chromatography coupled with mass spectrometry, GC\u2013MS, is described in the present work to identify and analyze the content of a wide variety of additives, commonly used in industrial polymeric materials. First, the identification under the present experimental protocol of additives with a relatively high molecular weight (Irganox 1330 and Irganox 1010) has been successfully attained. Second, the evolution under solar exposure over time has been analyzed by GC\u2013MS for 11 additives and derived substances, which have been identified in a commercial polypropylene sample, estimating the corresponding depletion times. In addition, the resultant increase of carbonyl groups in the polymeric macrochains along the photo-oxidation has been also determined by infrared spectroscopy. Therefore, GC\u2013MS is found to be a reliable tool for the analysis of the evolution of commonly used polymer additives under specific degradation conditions, which can be very useful in the formulation of improved future additivations.<\/jats:p>","DOI":"10.1021\/acsomega.9b03058","type":"journal-article","created":{"date-parts":[[2020,4,17]],"date-time":"2020-04-17T20:09:41Z","timestamp":1587154181000},"page":"9055-9063","source":"Crossref","is-referenced-by-count":45,"title":["Identification of Additives in Polypropylene and Their\nDegradation under Solar Exposure Studied by Gas Chromatography\u2013Mass\nSpectrometry"],"prefix":"10.1021","volume":"5","author":[{"given":"Enrique","family":"Bla\u0301zquez-Bla\u0301zquez","sequence":"first","affiliation":[{"name":"Instituto de Ciencia y Tecnologi\u0301a de Poli\u0301meros (ICTP-CSIC) , Juan de la Cierva 3 , ,","place":["Madrid, Spain, 28006"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4261-0627","authenticated-orcid":true,"given":"Mari\u0301a L.","family":"Cerrada","sequence":"additional","affiliation":[{"name":"Instituto de Ciencia y Tecnologi\u0301a de Poli\u0301meros (ICTP-CSIC) , Juan de la Cierva 3 , ,","place":["Madrid, Spain, 28006"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosario","family":"Benavente","sequence":"additional","affiliation":[{"name":"Instituto de Ciencia y Tecnologi\u0301a de Poli\u0301meros (ICTP-CSIC) , Juan de la Cierva 3 , ,","place":["Madrid, Spain, 28006"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5144-9268","authenticated-orcid":true,"given":"Ernesto","family":"Pe\u0301rez","sequence":"additional","affiliation":[{"name":"Instituto de Ciencia y Tecnologi\u0301a de Poli\u0301meros (ICTP-CSIC) , Juan de la Cierva 3 , ,","place":["Madrid, Spain, 28006"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2020,4,17]]},"reference":[{"key":"2026090209253031000_cit1","volume-title":"Additives for Polyolefins:\nGetting the Most Out of Polypropylene, Polyethylene and TPO","author":"Tolinski","year":"2015","edition":"2"},{"key":"2026090209253031000_cit2","volume-title":"Handbook for the Chemical\nAnalysis of Plastic and Polymer Additives","author":"Bolgar","year":"2016","edition":"2"},{"key":"2026090209253031000_cit3","first-page":"1","article-title":"Mass Spectrometry of Polymers \u2013 New Techniques","volume-title":"Advances in Polymer Science","author":"Hakkarainen","year":"2012"},{"key":"2026090209253031000_cit4","doi-asserted-by":"publisher","first-page":"2267","DOI":"10.1016\/j.polymdegradstab.2009.08.008","article-title":"Outdoor and\naccelerated\nweathering tests for polypropylene and polypropylene\/talc composites:\nA comparative study of their weathering behavior","volume":"94","author":"Azuma","year":"2009","journal-title":"Polym.
