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...
Hydroxyl-Terminated Poly(urethane acrylate) as a Soft Liner in Dental Applications: Synthesis and Characterization
Keskin, Selda; Usanmaz, Ali (Wiley, 2010-07-05)
Hydroxyl-terminated poly(urethane acrylate)s were synthesized for use in biomedical applications. Acrylate end capping via an interesterification reaction was successfully achieved with methacryloyl chloride addition to the hydroxyl ends of the polyurethane at low temperatures. 2,4-Toluene diisocyanate, 1,6-hexane diisocyanate, and methylene diphenyl diisocyanate were used as diisocyanates for urethane synthesis, and they were end-capped with methyl methacrylate and hydroxyethyl methacrylate. The nature of ...
Kinetics of polyurethane formation between glycidyl azide polymer and a triisocyanate
Keskin, S; Özkar, Saim (Wiley, 2001-07-25)
Kinetics of the polyurethane formation between glycidyl azide polymer (GAP) and a polyisocyanate, Desmodur N-100, were studied in the bulk state by using quantitative FTIR spectroscopy. The reaction was followed by monitoring the change in intensity of the absorption band at 2270 cm-l for NCO stretching in the IR spectrum, and was shown to obey second-order kinetics up to 50% conversion. The activation parameters were obtained from the evaluation of kinetic data at different temperatures in the range of 50-...
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 ...
Electrorheological properties of kaolinite, polyindole, and polyindole/kaolinite composite suspensions
Arslan, Yasin; Unal, Halil Ibrahim; Yilmaz, Hasim; Sari, Bekir (Wiley, 2007-06-05)
In this study, polyindole (PIN) and polyindole/kaolinite (PIN/KAO) composite were synthesized by free radical polymerization using FeCl3 as an initiator. Average particle sizes (d(50)) of PIN and PIN/KAO composite were determined by dynamic light scattering (DLS) as 7.2 and 6.2 mu m, respectively. The samples were characterized by FTIR, elemental analysis, DSC/TGA and SEM measurements. Suspensions of KAO, PIN, and PIN/KAO composite were prepared in silicone oil (SO) and the sedimentation stabilities were de...
