“…Kunar et al melt blended bisphenol-A polycarbonate and poly(butylene terephthalate) with ethylene-n-butylacrylate-glycidylmethacrylate terpolymer at various proportions in order to study the effects of compatibilizers on mechanical, thermal, and flow properties of the blends [ 22 ]. The studies concerning the PMMA/PC blend were reported by Macedo et al [ 23 ] The effect of processing conditions on the physicochemical properties of poly(methyl methacrylate)/polycarbonate blends was considered. The obtained polymer blends were characterized by a synergistic combination of mechanical properties of polycarbonate and polymethylmethacrylate.…”

This study presents the preparation and the thermo-mechanical characteristics of polymeric blends based on di(meth)acrylates monomers. Bisphenol A glycerolate diacrylate (BPA.GDA) or ethylene glycol dimethacrylate (EGDMA) were used as crosslinking monomers. Methyl methacrylate (MMA) was used as an active solvent in both copolymerization approaches. Commercial polycarbonate (PC) was used as a modifying soluble additive. The preparation of blends and method of polymerization by using UV initiator (Irqacure® 651) was proposed. Two parallel sets of MMA-based materials were obtained. The first included more harmless linear hydrocarbons (EGDMA + MMA), whereas the second included the usually used aromatic copolymers (BPA.GDA + MMA). The influence of different amounts of PC on the physicochemical properties was discussed in detail. Chemical structures of the copolymers were confirmed by attenuated total reflection–Fourier transform infrared (ATR/FT-IR) spectroscopy. Thermo-mechanical properties of the synthesized materials were investigated by means of differential scanning calorimetry (DSC), thermogravimetric (TG/DTG) analyses, and dynamic mechanical analysis (DMA). The hardness of the obtained materials was also tested. In order to evaluate the surface of the materials, their images were obtained with the use of atomic force microscopy (AFM).

“…Materials were mixed in two After extrusion mixing of the polymer blends, injection molding (test specimens, ASTM D638 Type I) was performed using an Arburg 270V system with temperature profile of 240/250/260/270/270°C and mold temperature of 40°C. Maintaining the same temperature profile used by Macedo et al [32] to guarantee the stability of the PMMAe/PC blend prevents thermal degradation from occurring during processing.…”

“…The development of the PMMAe/PC blend presented in previous studies by Macedo et al [32] showed that obtaining these polymer blends presented a synergistic combination of mechanical properties (due to the presence of core-shell particles in the PM-MAe) combined with the properties of polycarbonate and the type co-continuous morphology of the mixture. The aim of this work was to evaluate the fracture behavior of PMMAe/PC blend with…”

The aim of this study is to evaluate toughness mechanism of elastomeric poly(methyl methacrylate) (PMMAe) and polycarbonate (PC) blend through crack propagation at high speed tensile tests. Samples are processed using two types of extruders, single and twin screw, in order to eliminate the influence of processing in the final product's properties. Pure polymers and polymer blend samples are cryo‐ultramicrotomed and their morphology is characterized using atomic force microscopy (AFM). Fractured samples obtained from uniaxial tensile tests at high strain rate are inspected using optical microscopy (OM) and scanning electron microscopy (SEM). The results obtained for the PMMAe/PC blend in tests at high deformation rate showed that the shear rate during the mixing process influences the maximum strength of the polymer blend near its region of co‐continuous morphology. The visual evaluation of the fracture surface and the fractographic analysis corroborated the results of this study of polymer toughening.
