Influence of microstructure and deformation behavior on toughening of reactively compatibilized polyamide 6 and poly(ethylene-co-butyl acrylate) blends

Effects of nanotalc inclusion on mechanical, microstructural, melt shear rheological, and crystallization behavior of polyamide 6‐based binary and ternary nanocomposites

“…Ternary nanocomposites are formed to study the effect of simultaneous inclusion of elastomeric [ethylene‐ co ‐butyl acrylate (EBA)] and reinforcing nanofiller (nanotalc) on to a semi‐crystalline matrix (PA6) polymer, in which a simultaneous improvement in stiffness and toughness could be achieved with synergistically balanced mechanical properties. Very detailed studies on mechanical, morphological, rheological, and crystallization behavior of PA6/EBA blends via reactive compatibilization were published already [10–13]. A remarkable improvement in the toughness of PA6 was achieved in the reactively compatibilized blend, PA6/EBA‐ g ‐MAH/EBA, which was already reported in our previous work [11].…”

“…Very detailed studies on mechanical, morphological, rheological, and crystallization behavior of PA6/EBA blends via reactive compatibilization were published already [10–13]. A remarkable improvement in the toughness of PA6 was achieved in the reactively compatibilized blend, PA6/EBA‐ g ‐MAH/EBA, which was already reported in our previous work [11]. Optimum balance of stiffness (reinforcing property) and strain‐related properties (toughness) could be achieved by blending with optimum amount of nanotalc in PA6/EBA‐ g ‐MAH/EBA blend system.…”

“…Ethylene‐ co ‐butyl acrylate (EBA; Elvaloy 3427AC, density = 0.926 g/cc, butyl acrylate content = 27% and melt flow index of 4 g/10 min at 190°C, and load = 2.16 Kg), from DuPont industrial polymers (Wellington), was used as the minor component. EBA‐ g ‐MAH (EBA grafted with maleic anhydride) with 0.49% maleic anhydride content prepared by reactive extrusion in a twin screw extruder (TSE) was used as compatibilizer [11]. Nanotalc was received from Particle Technology laboratory, Department of Chemical Engineering, Indian Institute of Technology (Delhi, India).…”

Effect of the partially hydrolyzed EVA‐h content on the morphology, rheology, and mechanical properties of PA12/EVA blends

“…The particle size of the elastomeric dispersed phase was evaluated by means of the number‐average diameter ( ) and the volume‐average diameter ( ), obtained by : where N i and D i are, respectively, the number and the apparent diameter of the i th domain . For a sphere, the volume average radius of the dispersed phase it is half the diameter.…”

Polyoxymethylene/ethylene butylacrylate copolymer/ethylene‐methyl acrylate‐glycidyl methacrylate ternary blends

“…Ethylene butylacrylate copolymer (EBA) is an excellent toughening agent with high molecular polarity and good compatibility with many polymers. EBA has been used to toughen polyamide 6 and PLA , but has not been used as a toughening agent for POM yet. A compatibilizer is a very important component to prepare polymer blends as it can enhance the interfacial adhesion between the blend phases, and reactive compatibilization has been recognized as an effective method for producing blends .…”
