The Mag-CTA+ is an organophilic montmorillonite silicate clay prepared through a direct exchange process; the clay was modified by ultrasonic-assisted method using cetyltrimethylammonuim bromide in which it used as green nano-filler.The preparation method of nanocomposites was studied in order to determine and improve structural, morphological, mechanical and thermal properties ofsin.The structure and morphology of the obtained nanocomposites(Ros-Lim\/Mag-CTA+) were determined using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electronic microscopy and transmission electronic microscopy. The analyses confirmed the chemical modification of clay layers and the intercalation of rosin-limonene copolymer within the organophilic-clay sheets. An exfoliated structure was obtained for the lower amount of clay (1% wt of Mag-CTA+), while intercalated structures were detected for high amounts of clay (5 and 10% wt of Mag-CTA+). The thermal properties of the nanocomposites were studied by thermogravimetric analysis (TGA) and show a significant improvement inthe thermal stability of the obtained nanocomposites compared to the purerosin-limonene copolymer (a degradation temperature up to 280 \u00b0C).<\/jats:p>","DOI":"10.3390\/polym12091971","type":"journal-article","created":{"date-parts":[[2020,8,30]],"date-time":"2020-08-30T22:00:17Z","timestamp":1598824817000},"page":"1971","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Green Nanocomposites from Rosin-Limonene Copolymer and Algerian Clay"],"prefix":"10.3390","volume":"12","author":[{"given":"Hodhaifa","family":"Derdar","sequence":"first","affiliation":[{"name":"Centre de Recherche Scientifique et Technique en Analyses Physico-Chimiques (CRAPC), BP 10 384, Si\u00e8ge ex-Pasna Zone Industrielle, Bou-Ismail CP 42004, Tipaza, Algeria"},{"name":"Laboratoire de Chimie des Polym\u00e8res (LCP), D\u00e9partement de Chimie, FSEA, Oran1University Ahmed Benbella BP N 1524 El M\u2019Naouar, Oran 31000, Algeria"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7977-7610","authenticated-orcid":false,"given":"Geoffrey Robert","family":"Mitchell","sequence":"additional","affiliation":[{"name":"Centre for Rapid and Sustainable Product Development, Institute Polytechnic of Leiria, 2430-082 Marinha Grande, Portugal"}]},{"given":"Vidhura Subash","family":"Mahendra","sequence":"additional","affiliation":[{"name":"Centre for Rapid and Sustainable Product Development, Institute Polytechnic of Leiria, 2430-082 Marinha Grande, Portugal"},{"name":"School of Chemistry Food Science and Pharmacy, University of Reading, Reading RG6 6AD, UK"}]},{"given":"Mohamed","family":"Benachour","sequence":"additional","affiliation":[{"name":"Laboratoire de Chimie des Polym\u00e8res (LCP), D\u00e9partement de Chimie, FSEA, Oran1University Ahmed Benbella BP N 1524 El M\u2019Naouar, Oran 31000, Algeria"}]},{"given":"Sara","family":"Haoue","sequence":"additional","affiliation":[{"name":"Laboratoire de Chimie des Polym\u00e8res (LCP), D\u00e9partement de Chimie, FSEA, Oran1University Ahmed Benbella BP N 1524 El M\u2019Naouar, Oran 31000, Algeria"}]},{"given":"Zakaria","family":"Cherifi","sequence":"additional","affiliation":[{"name":"Centre de Recherche Scientifique et Technique en Analyses Physico-Chimiques (CRAPC), BP 10 384, Si\u00e8ge ex-Pasna Zone Industrielle, Bou-Ismail CP 42004, Tipaza, Algeria"},{"name":"Laboratoire de Chimie des Polym\u00e8res (LCP), D\u00e9partement de Chimie, FSEA, Oran1University Ahmed Benbella BP N 1524 El M\u2019Naouar, Oran 31000, Algeria"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0624-8480","authenticated-orcid":false,"given":"Khaldoun","family":"Bachari","sequence":"additional","affiliation":[{"name":"Centre de Recherche Scientifique et Technique en Analyses Physico-Chimiques (CRAPC), BP 10 384, Si\u00e8ge ex-Pasna Zone Industrielle, Bou-Ismail CP 42004, Tipaza, Algeria"}]},{"given":"Amine","family":"Harrane","sequence":"additional","affiliation":[{"name":"Laboratoire de Chimie des Polym\u00e8res (LCP), D\u00e9partement de Chimie, FSEA, Oran1University Ahmed Benbella BP N 1524 El M\u2019Naouar, Oran 31000, Algeria"},{"name":"Department of Chemistry, FSEI University of Abdelhamid Ibn Badis\u2014Mostaganem, Mostaganem 27000, Algeria"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0375-9314","authenticated-orcid":false,"given":"Rachid","family":"Meghabar","sequence":"additional","affiliation":[{"name":"Laboratoire de Chimie des Polym\u00e8res (LCP), D\u00e9partement de Chimie, FSEA, Oran1University Ahmed Benbella BP N 1524 El M\u2019Naouar, Oran 31000, Algeria"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1185","DOI":"10.1557\/JMR.1993.1185","article-title":"Mechanical properties of nylon 6-clay hybrid","volume":"8","author":"Kojima","year":"1993","journal-title":"J.
