摘要: A new grafted syndiotactic polystyrene (g-sPS), to be used as a compatibilizer for (sPS)/polyadimide 66 blends, was prepared by the melting graft copolymerization of sPS and monomers composed itaconic acid dibutyl maleate with dicumyl peroxide an initiator. The resulting g-sPS possessed side-chain structure identified IR spectra, results mechanical testing show that good impact strength tensile were obtained at 7.16-phr addition monomer 3:1 proportion acid. Differential scanning calorimetry electron microscopy analysis indicated maintained high glass-transition temperature crystalline structure. © 2005 Wiley Periodicals, Inc.
