The mechanical; morphological; and Theological properties of polymer blends based on polystyrene (PS) and three different types of polybutadiene (PB) were studied. The polymer blends containing 20% of PB were processed in a Haake mixer at 180°C and 60 rpm for 6 min. The materials exhibited impact strength superior to that of the PS. An increase was observed in the impact strength of 138; 208; and; 823%; when low-cis polybutadiene (PB1); high-cis polybutadiene (PBh); and styrene-butadiene block copolymer (PB co); were respectively used. The materials presented dispersed morphology with polybutadiene domains; with sizes inferior to 1 μm; randomly distributed in the PS matrix. The viscous and storage moduli increased as the applied frequency increased. The flow activation energy; calculated by Arrhenius equation; varied from 34 to 71 kJ/mol. In the rheological experiments all polymer blends presented pseudoplastic behavior; showing decreasing viscosities as the shear rate increased. © 2007 Wiley Periodicals; Inc;
