Compatibility study of waste poly(ethylene terephthalate) with poly(vinyl chloride). II

In this study, exploration of possibilities for use of recycled poly(ethylene terephthalate) (PET) in powder form as a filler in the PVC matrix was made. Powdered PET surfaces were modified by plasma to enhance the degree of interaction and, hence, the compatibilities. For modification, a series of different chlorine-containing monomers at two plasma operational conditions selected were used, in addition to the direct use of an oligomer of vinyl chloride. A series of mechanical, thermal, and surface energy analyses made with the composite samples prepared showed that it is possible to improve the properties by employing proper surface modification, which, in some cases, can even lead to synergestic results.

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...

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 po...
Viscoelastic characteristics of chain extended/branched and linear polyethylene terephthalate resins
Yılmazer, Ülkü; Xanthos, M; Bayram, Göknur; Tan, V (Wiley, 2000-03-01)
Two chemically modified chain extended/branched polyethylene terephthalate (PET) resins and one unmodified resin, considered to be linear, were characterized in terms of their melt flow, die swell, and viscoelastic properties. The three resins had reportedly similar nominal intrinsic viscosities but exhibited different viscoelastic behavior. The modified resins had lower melt flow index, higher die swell, higher complex viscosity and higher storage modulus than the unmodified one. The Cole-Cole plots of the...
Dynamic mechanical properties of dental base material reinforced with glass fiber
Karacaer, O; Dogan, A; Dogan, OM; Usanmaz, Ali (Wiley, 2002-08-22)
Dynamic mechanical properties of poly(methyl methacrylate) (PMMA) reinforced with glass fibers were investigated. The composite used as dental base material contained other additives for different purposes to give the same appearance as natural dentals. The fiber-polymer bonding and orientation of fibers in polymer matrix are very important in the application of the product. To see that, the fibers were treated with silane and compared with untreated fibers. The commercial polymer and monomer used were the ...
Mechanical properties of soft liner-poly(methyl methacrylate)-based denture material
Usanmaz, Ali; Latifoglu, MA; Dogan, A; Akkas, N; Yetmez, M (Wiley, 2002-07-18)
In this study, the mechanical properties of two different permanent soft lining materials and their bonding to poly(methyl methacrylate) (PMMA) were compared. Both of the soft liners were heat-cured commercial materials. The polymerization was carried out by conventional methods suggested by manufacturer, and the curing was done at the temperature of boiling water for 5, 15, 25, and 35 min. The sample groups were tested in the computer-aided tensile-testing machine at a rate of 2 mm/min. The slow rate helps...
