Effect of functionality levels and compatibility of polycarbonate blends with maleic anhydride grafted ABS
TLDR
In this article, three different modified ABSs were melt blended with polycarbonate using a single-screw extruder to choose a suitable maleic anhydride grafting level on ABS for better performance.Abstract:
ABS was melt grafted with maleic anhydride at three different levels of 1, 2, and 3 wt %. These three different modified ABSs were melt blended with polycarbonate using a single-screw extruder to choose a suitable maleic anhydride grafting level on ABS for better performance. For the compatibility study, binary blends of polycarbonate with ABS and maleic anhydride-grafted ABS were prepared over the entire range of compositions. Compatibility of these blends was studied using a Dynamic Mechanical Analyzer and by Differential Scanning Calorimetry. Both techniques suggest more partial compatibility for modified blend systems. In addition to this, DSC thermograms show multiple peaks between the transition points of ABS fractions and polycarbonate fractions for the polycarbonate/maleic anhydride-grafted ABS blends. These multiple peaks are characteristic of better partial compatibility with fine microstructure.read more

Rheology enhancement of polycarbonate/calcium carbonate nanocomposites prepared by melt-compounding
TL;DR: In this paper, the influence of calcium carbonate (CaCO3) nanoparticles on the rheology enhancement of polycarbonate (PC) melt was investigated, and it was shown that, upon incorporation of only 1 wt.% CaCO3, the tensile modulus, the bending modulus and the bending strength of PC are improved; however, the stiffness and elongation at break are depressed.

TL;DR: In this article, the effect of the filler on the structural, functional, morphological and thermal properties of a polyvinylidene fluoride (PVDF) matrix is investigated, and it is shown that the NiFe2O4 content in PVDF plays a significant role in controlling the conformation (α and β phases), and therefore has a significant effect on the ferroelectric and magnetic properties of the PVDF matrix.
