摘要
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 of PS—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 as a compatilizer of PS/EPDM blends and improved mechanical property and Thermal stability.Graft copolymerization reaction and degradation reaction are competitive in 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 Properties of blends decreased.关键词
