摘要

Abstract

The phase morphology

thermal behavior and mechanical properties of syndiotactic polystyrene/isotactic polypropylene (sPS/iPP) blends compatibilized by copolymer of syndiotactic polystyrene-b-poly(1-butene)(B30) were investigated.It was found that the typical morphology of an incompatible blend where iPP domains had a clear spherical shape in sPS matrix.However

compatibilizer B30 had an improved effect on the phase morphology of the resultant blends.DSC results showed that in these blends the onset temperature of the iPP-Tg region shifted toward the sPS-Tg

and the sPS-Tg shifted inward slightly.The typical blend of sPS/iPP/B30 = 90/10/10 coupled the best mechanical properties with unnotched izod impact strength 42.3 kJ/m2 and tensile strength 33.7 MPa.
