From a maleic anhydride (MA) grafted PP (PP‐g‐MA), the long‐branched chains are performed using [MA]/ [OH] reaction (with Sorbitol alcohol). On the other hand, short branched chains are made from the hydrolysis/condensation of amino‐alkoxysilane (3‐Aminopropyl‐triethoxysilane, APTES) in situ grafted onto PP chains through the ([MA]/NH2] reaction). The results show the need to combine both systems to reach the optimum of the rheological behavior (linear and non‐linear) to obtain a low‐density foam. On the other hand, the foaming behavior of polypropylene/polyamide 6 (PP/PA6) polymer blends at T = 180 °C is also investigated as another way to control the rheology and foamy behavior. At this temperature, T = 180 °C, the PA6 phase behaves as solid dispersed particles in a viscoelastic liquid PP matrix. Finally, this study shows the influence of PA6 concentration on the foaming and foam morphology correlated to a rheological study (shear and extensional) and mechanical compressive properties. Polypropylene chains with long and short branching are synthesized from PP‐g‐MA by reactive extrusion to obtain low‐density foams (&lt;100 kg m−3) using a batch scCO2 foaming process. The foaming behavior at T = 180 °C of compatibilized PP/PA6 blends is also investigated as another way to control the foaming behavior and the resulting mechanical properties.</description><identifier>ISSN: 1862-832X</identifier><identifier>EISSN: 1862-8338</identifier><identifier>DOI: 10.1002/mren.202200004</identifier><language>eng</language><publisher>Weinheim: Wiley Subscription Services, Inc</publisher><subject>Alkoxysilanes ; Aminopropyltriethoxysilane ; Carbon dioxide ; Chain branching ; Chemical Sciences ; CO2 ; Compressive properties ; Density ; foam ; Foaming ; Maleic anhydride ; Plastic foam ; Polyamide resins ; Polymer blends ; Polymers ; Polypropylene ; Rheological properties ; Rheology ; Sorbitol ; Viscoelastic liquids</subject><ispartof>Macromolecular reaction engineering, 2022-12, Vol.16 (6), p.n/a</ispartof><rights>2022 Wiley‐VCH GmbH</rights><rights>Distributed under a Creative Commons Attribution 4.0 International License</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c3914-5eb41a1bc4817b0fed4ca74e1f0d439bb46320333db8c0eed93d389b431062c03</citedby><cites>FETCH-LOGICAL-c3914-5eb41a1bc4817b0fed4ca74e1f0d439bb46320333db8c0eed93d389b431062c03</cites><orcidid>0000-0001-8217-8635 ; 0000-0003-4632-7060 ; 0000-0003-3651-3898</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>230,314,776,780,881,27903,27904</link.rule.ids><backlink>$$Uhttps://hal.science/hal-03857561$$DView record in HAL$$Hfree_for_read</backlink></links><search><creatorcontrib>Rainglet, Benoit</creatorcontrib><creatorcontrib>Verron, Lucas</creatorcontrib><creatorcontrib>Chalamet, Yvan</creatorcontrib><creatorcontrib>Bounor‐Legaré, Véronique</creatorcontrib><creatorcontrib>Delage, Karim</creatorcontrib><creatorcontrib>Forest, Charlène</creatorcontrib><creatorcontrib>Cassagnau, Philippe</creatorcontrib><title>New Reactive Formulations For Polypropylene Foams</title><title>Macromolecular reaction engineering</title><description>This work focuses on reactive extrusion to design polypropylene (PP) chains with long and short branching to obtain non‐linear behavior for the synthesis of low‐density foams (&lt;100 kg m−3) using a batch supercritical carbon dioxide (scCO2) foaming process.
