The influence of two UV photostabilizers on the photostability of Polyethylene-co-CHDM-terephthalate (PETG) and Polycyclohexylenedimethylene-Co-TMCD-terephthalate (PCTT) copolyester films was investigated. Untreated films and films containing stabilizer were irradiated. The resulting films were analyzed by attenuated total reflectance Fourier transform infrared (ATR FTIR) spectroscopy, gel permeation chromatography (GPC), and X-ray photoelectron spectroscopy (XPS). FTIR spectra of the irradiated films containing Cyasorb 1164 showed less change in intensity of the broad peak corresponding to OH groups, than the films containing Cyasorb 3638, indicating that Cyasorb 1164 is a better photostabilizer for these films. XPS results showed that the decrease in C/O ratio, due to photodegradation, was greater in films containing Cyasorb 3638 compared to those containing Cyasorb 1164. The formation of degradation products was evident from emission spectra arising from extracts of irradiated films based on PCTT +10% Cyasorb 3638, but no degradation products were apparent in extracts from irradiated PCTT +10% Cyasorb 1164. UV-absorption spectra of Cyasorb 1164 overlap more substantially with the absorption spectra of PETG and PCTT. The results from FTIR, XPS, and GPC analyses of the irradiated PETG and PCTT films demonstrated that Cyasorb 1164 was more effective than Cyasorb 3638 in enhancing resistance to UV-induced weathering.

Effect of Gas Permeation Temperature and Annealing Procedure on the Performance of Binary and Ternary Mixed Matrix Membranes of Polyethersulfone, SAPO-34, and 2-Hydroxy 5-Methyl Aniline Oral, Edibe Eda; Yılmaz, Levent; Kalıpçılar, Halil (Wiley, 2014-09-05) This study investigated the effect of annealing time and temperature on gas separation performance of mixed matrix membranes (MMMs) prepared from polyethersulfone (PES), SAPO-34, and 2-hydroxy 5-methyl aniline (HMA). A postannealing period at 120 degrees C for a week extensively increased the reproducibility and stability of MMMs, but for pure PES membranes no postannealing was necessary for stable and reproducible performance. The effect of operation temperature was also investigated. The permeabilities of...
Effect of composite preparation techniques on electrical and mechanical properties and morphology of nylon 6 based conductive polymer composites Koysuren, Ozcan; Yesil, Sertan; Bayram, Göknur (Wiley, 2006-11-05) Nylon 6/carbon black conductive composites were prepared using two different methods, masterbatch dilution and melt mixing. Their effect on the size and distribution of carbon black agglomerates in the matrix was studied in terms of electrical and mechanical properties and morphology. The electrical resistivity of composites prepared by both methods decreased with increasing filler composition. The electrical resistivity of the diluted masterbatch composites and the melt mixed composites was reduced from th...
Effects of olefin-based compatibilizers on the morphology, thermal and mechanical properties of ABS/polyamide-6 blends Ozkoc, Guralp; Bayram, Göknur; Bayramli, Erdal (Wiley, 2007-04-15) In this study, commercially available epoxidized and maleated olefinic copolymers, EMA-GMA (ethylene-methyl acrylate-glycidyl methacrylate) and EnBACO-MAH (ethylene-n butyl acrylate-carbon monoxide-maleic anhydride), were used at 0, 5, and 10% by weight to compatibilize the blend composed of ABS (acrylonitrile-butadiene-styrene) terpolymer and PA6 (polyamide 6). Compatibilizing performance of these two olefinic polymers was investigated from blend morphologies, thermal and mechanical properties as a functio...
Improved adhesive properties and bonding performance of HTPB-based polyurethane elastomer by using aziridine type bond promoter Gercel, BO; Üner, Deniz; Pekel, F; Özkar, Saim (Wiley, 2001-05-02) The effect of two aziridine-type bond promoters on adhesive and mechanical properties of a hydroxyl terminated polybutadiene-based elastomeric liner used in solid propellant rockets was investigated by varying the concentration to determine the optimum value. The performance of butyleneiminetrimesoylaziridine (BITA) was compared with that of tris[1-2-methylaziridinyl]phosphine oxide (MAPO) in the elastomeric liner of otherwise the same composition. The adhesive performance of the elastomer to the composite ...
Effects of Halloysite Nanotubes on the Performance of Plasticized Poly(lactic acid)-Based Composites Erpek, Canan Esma Yeniova; ÖZKOÇ, GÜRALP; Yılmazer, Ülkü (Wiley, 2016-11-01) The objective of this study is processing and characterization of Halloysite nanotube (HNT)/poly(lactic acid) (PLA) nanocomposites. As HNT filler, a domestic source was used (ESAN HNT). The results obtained from this HNT were compared with a well-known reference HNT (Nanoclay HNT). To achieve the desired physical properties and clay dispersion, composites were compounded via direct melt mixing in a laboratory twin-screw compounder. However, the constituents were observed to be incompatible without a compati...
