Impact modified epoxy/montmorillonite nanocomposites: synthesis and characterization
Isik, I; Yılmazer, Ülkü; Bayram, Göknur (2003-09-01)
Diglycidyl ether of bisphenol A type epoxy resin-polyether polyol-organically treated montmorillonite ternary nanocomposites were synthesized in this study. The effects of addition of polyether polyol as an impact modifier on morphological, thermal and mechanical properties of nanocomposites were investigated by X-ray diffraction, scanning electron microscopy (SENI), differential scanning calorimetry, impact and tensile testing. The results showed that organically treated montmorillonite is intercalated by ...
Impact modified polyamide-6/organoclay nanocomposites: Processing and characterization
Isik, Isil; YILMAZER, ÜLKÜ; Bayram, Göknur (Wiley, 2008-02-01)
The effects of melt state compounding of ethylene-butyl acrylate-maleic anhydride (E-BA-MAH) terpolymer and/or three types of organoclays (Cloisitel(R) 15A, 25A, and 3013) on thermal and mechanical properties and morphology of polyamide-6 are investigated. E-BA-MAH formed spherical domains in the materials to which it is added, and increased the impact strength, whereas the organoclays decreased the impact strength. In general, the organoclays increased the tensile strength (except for Cloisite 15A), Young'...

Polystyrene, PS, is a preferable polymer in industry, but, its brittle characteristic restricts its utilization. The aim of this study is to improve the impact strength of PS by the help of elastomeric materials SEBS-g-MA and E-BA-GMA. In order to prevent the reduction in the tensile strength of the materials, three different types of organic montmorillonites, MMT, (Cloisite® 30B, 25A and 15A) were used as fillers. Nanocomposite preparation was performed in a co-rotating twin screw extruder. Initially elast...
Impact modified poly(ethylene terephthalate)-organoclay nanocomposites
Alyamaç, Elif; Yılmazer, Ülkü; Department of Chemistry (2004)
This study was conducted to investigate the effects of component concentrations and addition order of the components, on the final properties of ternary nanocomposites composed of poly(ethylene terephthalate), organoclay, and an ethylene/methyl acrylate/glycidyl methacrylate (E-MA-GMA) terpolymer acting as an impact modifier for PET. In this context, first, the optimum amount of the impact modifier was determined by melt compounding binary PET-terpolymer blends in a corotating twin-screw extruder. The amoun...
Impact modified polyamide-organoclay nanocomposites
Işık, Işıl; Yılmazer, Ülkü; Department of Chemical Engineering (2007)
The effects of melt state compounding and addition order of ethylene-butyl acrylate-maleic anhydride (E-BA-MAH), ethylene-glycidyl methacrylate (E-GMA), ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) terpolymer and/or three types of organoclays (Cloisite® 15A, 25A and 30B) on morphology, thermal, mechanical and dynamic mechanical properties of polyamide-6 are investigated. XRD patterns show that the interlayer spacing for Cloisite® 15A remained unchanged; however it increased for the organoclays ...
