Polymerization and characterization of 2-Hydroxyethyl acrylate
Vargün, Elif; Usanmaz, Ali; Department of Polymer Science and Technology (2003)
Poly(2-Hydroxyethyl acrylate), PHEA, is used as hydrophilic polymeric gels which have been studied because of its great importance for agricultural or biomedical applications. Biomedical applications of hydrogels include soft contact lenses, artificial corneas, soft tissue substitutes and burn dressings. In this study, it was aimed to synthesis the polymers with well-defined molecular weights, polydispersities and cahin topologies. Bulk, solution and atom transfer radical polymerization (ATRP) techniques at...
Polymerization and characterization of methylmethacrylate by atom transfer radical polymerization
Aran, Bengi; Usanmaz, Ali; Department of Polymer Science and Technology (2004)
In this work, methylmethacrylate, MMA was polymerized by ATRP method to obtain low molecular weight living polymers. The initiator was p-toluenesulfonylchloride and catalyst ligand complex system were CuCl-4,4̕ dimethyl 2,2̕bipyridine. Polymers with controlled molecular weight were obtained. The polymer chains were shown by NMR investigation to be mostly syndiotactic. The molecular weight and molecular weight distribution of some polymer samples were measured by GPC method. The K and a constants in [h]=K Ma...
Polymerization and polymer characterization of n-vinylcaprolactam
Polat, Özlem; Usanmaz, Ali; Department of Polymer Science and Technology (2005)
In this study, N-vinylcaprolactam was polymerized by radiation in the solid state. The polymerization was carried out at room temperayure under vacuum and open to atmosphere respectively. The polymerization mechanism showed autoacceleration and the rate of polymerization was higher in the presence of oxygen. However the limiting conversion was 100% under vacuum conditions and 90% in the present of oxygen. This is due to the low molecular weight olgomer formation in the presence of oxygen. The polymers were ...

POLYMERIZATION OF ALLYLTHIOUREA BY CONSTANT-CURRENT ELECTROLYSIS
OZKAN, H; Usanmaz, Ali; ONAL, MA (Wiley, 1994-11-01)
Allylthiourea was polymerized by constant current electroinitiation in acetonitrile using tetrabutylammonium fluoroborate as supporting electrolyte. The polymer obtained was insoluble in common organic solvents. FTIR studies showed that polymerization propagates by addition through the C=C double bond. The cyclic voltammogram of the monomer gave two irreversible oxidation peaks at + 1.3 V and + 2.4 V versus Ag-degree/Ag+ reference electrode at 25-degrees-C. Polymerization at room temperature gave a limi...
