“…The r-PC/r-ABS blends may also include PMMA as a third component (Laverty et al 1996;Rybnicek et al 2005). In this case, the chemical composition of the styrene-acrylonitrile matrix of ABS was found to have a dramatic effect on the morphology, while lubricant additives of ABS are adverse to the chemical stability.…”

“…However, all the compositions rich in PMMA exhibited inferior mechanical performance (Laverty et al 1996). A more detailed mechanical study (Rybnicek et al 2005) demonstrated that the transition from ductile elastoplastic behavior to brittle linear elastic fracture behavior occurs when the PMMA is above 10 wt%.…”

“…The surfaces of molded specimens were observed using a Hitachi S‐416, Japan (FE‐SEM) scanning electron microscope after sputter gold coating. The samples were cryogenically fractured and etched with a permanganic etching agent (solution containing 0.7 g of KMnO 4 , 20 mL of concentrated sulfuric acid, and 20 mL of phosphoric acid) to visualize PMMA and polybutadiene in ABS matrix 41. The surface of the specimens was immersed into the prepared solution for 15 min and then washed in running water.…”

The effect of three types of organoclays on the morphology and mechanical properties of lower critical solution temperature-type poly(acrylonitrile-butadiene-styrene)/poly(methyl methacrylate) (ABS/PMMA) blends was investigated. Polymers were melt-compounded with 2 and 4 wt % of clays using a twin-screw extruder. X-ray scattering and transmission electron microscopy revealed that the intercalation of the nanoclay in the hybrid nanocomposite was more affected by the polarity of the organoclay. Although the morphology of the blends varied by PMMA content, scanning electron microscopy showed smaller PMMA domains for the hybrid systems containing clay par-ticles. Although good dispersion of the nanoclay through the ABS matrix and at the blend interface led to enhancement of tensile strength, the increment of the stiffness was more noticeable for nanocomposites including less polar organoclay. Well-dispersed clay platelets increased the glass transition temperature. In addition, nanoscratching analysis illustrated an improvement in scratch resistance of ABS because of the presence of PMMA and organoclay.

“…In a study of ABS degradation, Liu and coworkers showed that the polybutadiene (PB) phase was obviously reduced and that the styrene and acrylonitrile units remained relatively stable. This was due to the fact that the double bonds in the PB phase are prone to breakage; this results in a decrease in the molecular weight of the ABS and phase separation between the matrix and PB phase . These phenomena also exist during the degradation of PC/ABS blends.…”

To improve the utilization efficiency of recycled polycarbonate/acrylonitrile-butadiene-styrene (R-PC/ABS), we studied the mechanical, morphological, and rheological properties of R-PC/ABS with styrene-butadiene-glycidyl methacrylate (SBG), which was used to reinforce and toughen the R-PC/ABS through chemical compatibilization. Fourier transform infrared spectroscopy demonstrated that carboxyl and hydroxyl groups in R-PC/ABS reacted with epoxy groups in SBG to produce ester and ether groups. The results of scanning electron microscopy show that the domain sizes of the ABS particles decreased when the SBG content was 6 wt %; this demonstrated that the compatibility of the polycarbonate (PC) and ABS was improved after the addition of SBG. The results of the loss modulus of dynamic mechanical analysis were consistent with the morphological results, which reflected a better compatibility of PC and ABS in the modified samples. The introduction of SBG increased the molecular weight and entanglements; this improved the viscosity and storage modulus in the modified samples, as demonstrated by the rheological results. Furthermore, the mechanical properties were obviously enhanced, especially the impact strength, when the SBG content was 6 wt %; this was ascribed to the chemical reactions and improved compatibility after melt extrusion with SBG.
