This strategy improves the poor processing fluidity of composites and solves the impossibility of conducting extrusion in one step via using microcapsule-type crosslinking agents prepared by in situ polymerization to co-extrude with PVC blends. The results demonstrate that the PVC\/microcapsule composites were successfully prepared. Within the studied parameters, the properties of crosslinked PVC gradually increased with the addition of microcapsules, and its Vicat softening temperature increased from 79.3 \u00b0C to 86.2 \u00b0C compared with pure PVC. This study shows the possibility for the industrial scale-up of the extrusion process for rigid crosslinked PVC.<\/jats:p>","DOI":"10.3390\/ma16134600","type":"journal-article","created":{"date-parts":[[2023,6,26]],"date-time":"2023-06-26T05:28:02Z","timestamp":1687757282000},"page":"4600","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A Novel One-Step Reactive Extrusion Process for High-Performance Rigid Crosslinked PVC Composite Fabrication Using Triazine Crosslinking Agent@Melamine-Formaldehyde Microcapsules"],"prefix":"10.3390","volume":"16","author":[{"given":"Jinshun","family":"Zhao","sequence":"first","affiliation":[{"name":"Hubei Provincial Key Laboratory of Green Materials for Light Industry, School of Materials and Chemical Engineering, Hubei University of Technology, Wuhan 430068, China"},{"name":"Beijing Key Laboratory of Ionic Liquids Clean Process, Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of Ionic Liquids Clean Process, Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiayang","family":"Sui","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of Ionic Liquids Clean Process, Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuai","family":"Jiang","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of Ionic Liquids Clean Process, Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weizhen","family":"Zhao","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of Ionic Liquids Clean Process, Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100190, China"},{"name":"Longzihu New Energy Laboratory, Zhengzhou Institute of Emerging Industrial Technology, Henan University, Zhengzhou 450046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shihao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Hubei Provincial Key Laboratory of Green Materials for Light Industry, School of Materials and Chemical Engineering, Hubei University of Technology, Wuhan 430068, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rong","family":"Wu","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of Ionic Liquids Clean Process, Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jintong","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of Ionic Liquids Clean Process, Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5002-0806","authenticated-orcid":false,"given":"Xuhuang","family":"Chen","sequence":"additional","affiliation":[{"name":"Hubei Provincial Key Laboratory of Green Materials for Light Industry, School of Materials and Chemical Engineering, Hubei University of Technology, Wuhan 430068, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"122198","DOI":"10.1016\/j.polymer.2020.122198","article-title":"Effects of chlorinated polyethylene and antimony trioxide on recycled polyvinyl chloride\/acryl-butadiene-styrene blends: Flame retardancy and mechanical properties","volume":"190","author":"Li","year":"2020","journal-title":"Polymer"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1767","DOI":"10.3390\/polym7091482","article-title":"Preparation and characterization of novel PVC\/silica-lignin composites","volume":"7","author":"Klapiszewski","year":"2015","journal-title":"Polymers"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"586","DOI":"10.1016\/j.clay.2015.07.008","article-title":"Effects of the metakaolin-based geopolymer on high-temperature performances of geopolymer\/PVC composite materials","volume":"114","author":"Wang","year":"2015","journal-title":"Appl.
