Effect of Talc and Synthetic Sodium Aluminum Silicate (SSAS) on the Properties of PC/PMMA Blend

摘要

The advent of plastics and the wide range of fillers that are available have made modifications as precise as the tailored resins themselves.To modify the properties of polymer either by using fillers or by preparation of polymer blends gives rise to new materials with tailored properties.More complex,three-component systems,obtained by the addition of inorganic filler to an immiscible blend may be of interest.Blends of polycarbonate (PC) with poly(methyl methacrylate) (PMMA) exhibit improved toughness characteristics via a two-phase structure.In this investigation the effect of talc and synthetic sodium aluminum silicate (SSAS) as fillers on properties of PC/PMMA blends has been examined.The neat blends of PC at different concentrations of PMMA were studied for their mechanical,electrical,and rheological properties.It was observed that 75/25 PC/PMMA blend showed more improved properties than that of individual polymers and hence was used to study the effect of filler loading on mechanical,electrical,and rheological properties.
