Ternary polymer blend with core–shell dispersed phases: effect of the core-forming polymer on phase morphology and mechanical properties

摘要: Abstract Phase morphology and mechanical properties of ternary blends consisting PS (polystyrene), SBR (styrene butadiene rubber) different polyolefins (POs) have been studied. PS, systematically forms the matrix, PO being combined in dispersed phase. Although POs various melt viscosity stiffness are used, binary (SBR/PO) phase is a core–shell structure, which core. Upon increasing PO, average size cores domains including them increases. Comparison experimental shear storage modulus with theoretical predictions indicates that stress transfer from matrix to core through shell depends on envelope. The ultimate sensitive
