接枝共聚物WPS-g-POE的制备及其在三元乙丙橡胶中的应用
|
摘要
通过Friedel-Crafts烷基化反应制备接枝共聚物废旧聚苯乙烯(WPS)-g-聚烯烃弹性体(POE),研究WPS-g-POE用量对三元乙丙橡胶(EPDM)性能的影响。结果表明:预处理WPS可以与POE发生Friedel-Crafts烷基化反应,生成WPS-g-POE,WPS接枝率为28. 8%,凝胶含量为0;添加WPS-g-POE的硫化胶物理性能和耐热空气老化性能优于添加WPS/POE共混物的硫化胶以及未添加WPS/POE共混物和WPS-g-POE的硫化胶,添加10份WPS-g-POE的硫化胶综合物理性能最佳;与添加WPS/POE共混物的硫化胶相比,添加WPS-g-POE的硫化胶中WPS分散更均匀、粒子更细小。
The graft copolymer,waste polystyrene(WPS)-g-polyolefin elastomer(POE),was prepared by Friedel-Crafts alkylation reaction,and the effect of WPS-g-POE amount on the properties of ethylenepropylene-diene rubber(EPDM) was investigated. The results showed that,the pretreated WPS generated Friedel-Crafts alkylation reaction with POE to form WPS-g-POE,the grafting ratio of WPS was 28. 8%,and the gel content was 0. The physical properties and hot air aging resistance of the vulcanizates with WPSg-POE were superior to those of the vulcanizates without WPS-g-POE,or with WPS/POE blend. The comprehensive physical properties of the vulcanizates with 10 phr WPS-g-POE were the best. Compared with the vulcanizate with WPS/POE blend,the vulcanizate with WPS-g-POE had more uniform dispersion and finer particles.
