Four different types of high-density polyethylenes (HDPE) were blended with perlite at different concentrations. Silane coupling agent gamma-aminopropyltriethoxy silane (gamma-APS, A-1100) was used to enhance the adhesion between perlite and HDPEs. Ultimate tensile strength and elastic modulus increased as the perlite content increased, while ultimate elongations decreased with the increasing amount of perlite. Exceptional variations in the measured properties are explained in terms of the differences in polyethylenes used in the composites. The biggest improvement in ultimate tensile strength was observed in the highly crystalline polyethylene; on the other hand, in the absence of silane coupling agent the high molecular weight polyethylene showed the least improvement in tensile strength. The effect of branching in HDPE composites was demonstrated. The enhancement of interfacial adhesion by using a coupling agent was also examined by scanning electron microscopy (SEM).

Preparation and characterization of poly(ethylene terephthalate) powder-filled high-density polyethylene in the presence of silane coupling agents Demir, T; Tincer, T (Wiley, 2001-01-31) Micron-size crystalline particles of Poly(ethylene terephthalate) (PET), obtained from PET bottles by crystallization and grinding, were used as a filler in high-density polyethylene (HDPE). The composite of PET particle-filled HDPE was prepared by melt mixing at 190 degreesC, which was well below the melting temperature of PET. Silane coupling agents (SCAs) were used to enhance the interaction between PET and HDPE in the composite. A chain extender (CE) and maleic anhydride (MA) were also used to provide f...
Reactive processing and properties of styrene-maleic anhydride and poly(tetramethylene ether glycol) Bayram, G; Yılmazer, Ülkü (Wiley, 2002-03-07) The anhydride/hydroxyl-functionalized blends of styrene-maleic anhydride (SMAH) with poly(tetramethylene ether glycol) (PTMEG) in the presence or absence of a hydrated zinc acetate catalyst were produced in a batch mixer and in a corotating twin-screw extruder. In batch mixing, torque values increased with time as a result of chain-extension/branching reactions. The reaction products were studied by thermal, mechanical, morphological, and spectroscopic characterization techniques. The glass transition tempe...
Preparation and characterization of thermally stable phosphonium organoclays and their use in poly(ethylene terephthalate) nanocomposites Abdallah, Wissam; Yılmazer, Ülkü (Wiley, 2013-06-15) Purification of montmorillonite rich bentonite followed by surface modification using organic salts was performed. The bentonite was purified by sedimentation and then surface modified by ion exchange using alkyl- and aryl-based phosphonium salts. The thermal stability, morphology, melt flow, and mechanical properties of the poly(ethylene terephthalate) (PET) nanocomposites prepared with these organoclays were studied with and without using a reactive elastomeric compatibilizer. TEM results showed that the ...
Synthesis and electro-optical properties of a new copolymer based on EDOT and carbazole Akbayrak, Merve; Önal, Ahmet Muhtar (Informa UK Limited, 2016-01-01) A new copolymer of 3,4-ethylenedioxythiophene (EDOT) and 5-(2-ethylhexyl)-1,3-bis(9-methyl-9H-carbazol-3-yl)-5H-thieno[3,4-c]pyrrole-4,6-dione (CzPDICz) was electrochemically synthesized using different monomer feed ratios. The resulting copolymer films were investigated in terms of their electrochemical and electro-optical behaviors. Properties of the obtained copolymer films through different monomer feed ratios were compared to each other and to individual poly(ethylenedioxythiophene; PEDOT) and homopoly...
Preparation and characterization of W/O/W type double emulsion containing PGPR-lecithin mixture as lipophilic surfactant ALTUNTAS, Ozlem Yuce; Şümnü, Servet Gülüm; Şahin, Serpil (Informa UK Limited, 2017-01-01) The objective of this study is to produce double emulsion by combining polyglycerol polyricinoleate (PGPR) with lecithin as lipophilic surfactant. Although lecithin alone produced only oil-in-water type emulsion, the mixture of lecithin and PGPR could produce water-in-oil type emulsion as well. Moreover, different emulsification treatments were applied to study the influence of homogenization methods on the physicochemical characteristics. The obtained double emulsions were compared in terms of stability an...
