摘要:
利用Friedel-Crafts烷基化反应就地增容PS/EPDM合金,考察了无水AlCl3用量对PS与EPDM间Friedel-Crafts烷基化反应及合金性能的影响。结果显示:加入适量的无水AlCl3可以引发PS、EPDM间产生Friedel-Crafts烷基化反应,生成PS-g-EPDM接枝共聚物; 该接枝物起到相容剂作用,使PS/EPDM合金的力学性能、热稳定性等得到显著提高; 反应体系存在接枝和降解两种竞争反应; 加大AlCl3用量后,由于PS、EPDM分子链的降解反应起主导作用,合金的性能降低。
Abstract:
PS/EPDM melting blends were in-situ compatibilized by Friedel-crafts alkylation reaction.Effects of the amount of anhydrous aluminum chloride(AlCl3)on Friedel-Crafts alkylation between polystyrene(PS)and EPDM and properties of PS/EPDM blends were examined.The results showed that a copolymer ofPS-g-EPDM can be formed during melting of blends via a Friedel-Crafts benzene ring alkylation with moderate catalyst amount.The grafting co-polymer behaved asa compatilizer of PS/EPDM blends and improved mechanical property and Thermal stability.Graft copolymerization reaction and degradation reaction are competitivein the reaction system. when the amount of AlCl3 was increased, the properties of blends became worse due to the chain scission of PS and EPDM and Propertiesof blends decreased.
