A series of poly(methyl methacrylate-co-hydroxyethyl methacrylate) (PMMA-co-PHEMA), copolymers were synthesized by an emulsion polymerization technique. Copolymer compositions were determined by FT-IR and 1H-NMR spectroscopy. It was found that comonomer ratios used in the recipes were comparable within the actual copolymers. Glass transition temperatures (Tg) of PMMA-co-PHEMA copolymers were varied from 119 degrees C to 100 degrees C by increasing HEMA content. Thermogravimetric analysis showed that the copolymers were stable up to 330 degrees C. High intrinsic viscosity values of copolymer resulted in ductile solution-cast films. The hydrophilicity of the films was analyzed by water uptake measurements.

Synthesis and Characterization of Conducting Copolymers of Bisphenol A-Diglycidyl Ether with Thiophene Side-Groups and Pyrrole
Sahmetlioglu, Ertugrul; Varol, Ramazan; Toppare, Levent Kamil; Yuruk, Huseyin (Informa UK Limited, 2009-01-01)
Copolymers of bisphenol A-diglycidyl ether with thiophene side-groups and pyrrole were synthesized by electrochemical polymerization. Bisphenol A-diglycidyl ether with thiophene side-groups (DGEBATh) was obtained from the reaction between bisphenol A-diglycidyl ether (DGEBA) and thiophene-3-acetic acid. The syntheses of copolymers of DGEBATh and pyrrole were achieved electrochemically using three different supporting electrolytes, p-toluene sulfonic acid (PTSA), sodium dodecyl sulfate (SDS) and tetrabutylam...

Gunaydin, O; Toppare, Levent Kamil; Yagci, Y; Harabagiu, V; Pintela, M; Simionescu, BC (Springer Science and Business Media LLC, 2002-02-01)
Polysiloxane-polypyrrole graft copolymers have been synthesized by a series of chemical reactions and subsequent electropolymerization. First, the hydrosilation of 4-vinyl aniline by dimethyl-methylhydrosiloxane copolymer gave the corresponding aminophenyl functional polydimethylsiloxane (PDMS-NH2). The side chain pyrrole functionalized. polysiloxanes were then prepared by the reaction of PDMS-NH2 with glycidylpyrrole. Finally, the synthesis of graft copolymers of polysiloxane and pyrrole has been achieved ...
Synthesis and Characterization of Polypyrrole Nanoparticles and Their Nanocomposites with Poly(propylene)
Sevil, Baytekin; Zuhal, Kucukyavuz (2009-07-09)
Conducting polypyrrole (PPy) nanoparticles were synthesized via microemulsion polymerization. PP/PPy nanocomposites were prepared by melt-mixing of polypyrrole with polypropylene (PP) and processed with injection molding. Tensile tests have revealed that increasing amount of PPy increased the strength and the stiffness of the nanocomposite while limiting the elongation of PP. Thermal gravimetric analysis has showed that incorporation of PPy nanoparticles has improved the thermal stability of the nanocomposi...
Preparation of a conducting flexible material from silane coupling agent and hydroxyl terminated polybutadiene rubber by hydrolysis and condensation
Karatas, Y; Toppare, Levent Kamil; Tincer, T (Informa UK Limited, 2003-01-01)
Synthesis and characterization of a flexible polymer produced from silane coupling agent (SCA) and hydroxyl terminated polybutadiene (HTPB) were performed. Mechanical properties of chemically and electrochemically prepared conducting composites synthesized from this polymer were investigated. Conductivities of the composites were also measured. Polypyrrole enhanced the mechanical properties of the chemically prepared conducting composite. Doping with iodine greatly changed the conductivity of the composite....

2-[(3-Thienylcarbonyl)oxy]ethyl 3-thiophene carboxylate (TOET) was synthesized via the reaction of 3-thionylcarboxylic acid with ethylene glycol, and electrochemically polymerized with thiophene (Th) and pyrrole (Py) by using tetrabutylannnonium tetrafluoroborate (TBAFB) as the supporting electrolyte in acetonitrile (ACN). Characterization of the resulting copolymers were performed via cyclic voltammetry, FTIR, and scanning electron microscopy (SEM). Electrical conductivities are measured by the four-probe ...
