In this study, ethyl methacrylate was polymerized by free radical polymerization at 600C, 700C, 800C at open atmosphere; atom transfer radical polymerization, (ATRP), at 800C in vacuum and in gamma irradiation in vacuum. The polymer obtained was white, hard material. The kinetic curves for free radical polymerization and ATRP by gamma radiation were S-type. However, the curve for polymerization by gamma irradiation raises more smoothly. For ATRP by thermal initiation gives a lineer change of conversion with time. It was observed that the molecular weight can be controlled and low molecular weight polymer could be obtained by ATRP method. The characterization of polymers were made by FTIR, DSC, 1H and 13C NMR techniques.

Polymerization of 2-hydroxyethyl acrylate in bulk and solution by chemical initiator and by ATRP method
Vargun, E; Usanmaz, Ali (Wiley, 2005-09-01)
In this study, 2-hydroxyethyl acrylate (HEA) was polymerized to obtain polymers that can be used as hydrogel and copolymerized for biomedical applications. Bulk, solution, and atom transfer radical polymerization (ATRP) techniques at different temperatures were applied. The polymerization in bulk form was carried out in vacuum and in open atmosphere. The polymerization curves showed autoacceleration mechanism and the limiting conversion was 100%. The polymers obtained were insoluable in most common solvents...
Synthesis and characterization of electrochemically polymerized metal-free, nickel and zinc containing phthalocyanine derivatives
Yavuz, Arzu; Aras, Leyla; Department of Polymer Science and Technology (2009)
In the first part of this study, 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-phthalonitrile (SNS-PN) was synthesized by utilizing 1,4-di(2-thienyl)-1,4- butadione (SOOS) and 4-aminophthalonitrile via Knorr-Paal Reaction. Nuclear magnetic resonance (1H NMR and 13C NMR) and fourier transform infrared (FTIR) spectroscopies were utilized for the characterization of this compound. SNS-PN monomer was then electrochemically polymerized in acetonitrile/0.2 M LiClO4 solvent/electrolyte couple. Characterizations of the re...
Synthesis and characterization of hyperbranched and air drying fatty acid based resins
Bat, Erhan; Kisakurek, D; Akhmedov, IM (Elsevier BV, 2006-04-01)
In this research four hyperbranched resins having fatty acid residues were synthesized. Dipentaerythritol, which was used as the core molecule of the resins, was twice esterified with dimethylol propionic acid. This resin was then esterified with the castor oil fatty acids. The hydroxyl group present in the ricinoleic acid which constitutes almost 87% of the castor oil fatty acids was then reacted with linseed oil fatty acids and benzoic acid. The linseed fatty acids were incorporated into the structure to ...
Synthesis of block copolymers by combination of photoinduced and atom transfer radical polymerization routes
Erel Göktepe, İrem; Serhatli, Ersin; Yağcı, Yusuf (2002-01-01)
Block copolymers of methyl methacrylate (MMA) and styrene (St) were obtained by the combination of two different free radical polymerization processes, namely photoinduced and atom transfer radical polymerization (ATRP) methods. In the first step, hydroxy terminated polymers were prepared by photoinitiated polymerization of MMA in the presence of N,N'-dimethylethanolamine and benzophenone as the initiating system and subsequently converted to bromine ended poly(methyl methacrylate) by the esterification of ...
Solid State Polymerization of N-vinylcaprolactam via Gamma Irradiation and Characterization
Usanmaz, Ali; Ozdemir, Tonguc; Polat, Özlem (Informa UK Limited, 2009-01-01)
In this study, N-vinylcaprolactam was polymerized via gamma irradiation in the solid state. The polymerization was carried out at room temperature both under vacuum and open to atmosphere. The polymerization mechanism showed auto acceleration and the rate of polymerization was higher in the presence of oxygen. Complete conversion was obtained under vacuum conditions and 90% conversion was obtained in the case of polymerization open to atmosphere. The polymers were characterized by FTIR, NMR, DSC, TGA, GPC, ...
