Preparation of graft and branched polymers via photo-induced radical polymerization and photo-induced self-condensing vinyl polymerization (SCVP) routes, respectively, was studied. Precursor random co-polymers of styrene (St) and 2-(dimethylamino)ethyl methacrylate (DAEMA) were obtained via thermal polymerization initiated by azoisobutyronitrile, (AIBN) and used as macromolecular co-initiators in photo-induced grafting experiments. Successful grafting was achieved, while cross-linking also occurred to some extent. The resulting graft co-polymers were characterized by H-1-NMR and GPC measurements. The synthesis of branched polymers was carried out by the use of DAEMA as an inimer in photoinduced SCVP, in which irradiations were performed in a photoreactor emitting light with a wavelength of 350 nm. Surface morphologies of branched and linear polymers were examined by atomic force microscopy (AFM) and compared.

Synthesis and mesophase properties of block and random co-polymers of electroactive and liquid crystalline monomers Yilmaz, F; Kasapoglu, F; Hepuzer, Y; Yagci, Y; Toppare, Levent Kamil; Fernandes, EG; Galli, G (Informa UK Limited, 2005-01-01) Homo-polymers and random co-polymers of electroactive and liquid crystalline monomers, namely 3-thienylmethyl methacrylate (MTM) and 6-(4-cyanobiphenyl-4'-oxy)hexyl acrylate (LC6), were prepared by conventional free radical polymerization. Block co-polymers of MTM and LC6 were also synthesized by using the 1,1-diphenylethene (DPE) method. The obtained random and block co-polymers exhibited liquid crystal behavior depending on the content of the LC6 units. It was found that microphase separation of the polym...
Synthesis of a novel fluorescent and ion sensitive monomer bearing quinoxaline moieties and its electropolymerization Carbas, Buket Bezgin; KIVRAK, Arif; Zora, Metin; Önal, Ahmet Muhtar (Elsevier BV, 2011-05-01) A novel terthienyl based fluorescent polymer bearing pendant quinoxaline moieties directly attached to the 3-positions of the central thiophene ring was synthesized by electrochemical polymerization of 4-((2,5-dithiophen-2-yl)thiophen-3-yl)pyrrolo[1,2-a]quinoxaline (TT-Q). The corresponding polymer was characterized by cyclic voltammetry, FT-IR and UV-vis spectroscopy. The polymer exhibits a reversible redox behavior (Ep(1/2) = 1.05 V) accompanied with a reversible electrochromic behavior; yellowish orange ...
Synthesis and Characterization of 2-Hydroxyethyl Methacrylate (HEMA) and Methyl Methacrylate (MMA) Copolymer Used as Biomaterial Vargun, Elif; SANKIR, MEHMET; Aran, Bengi; DEMİRCİ SANKIR, NURDAN; Usanmaz, Ali (Informa UK Limited, 2010-01-01) 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 cop...
Synthesis and characterization of thiophen-3-yl acetic acid 4-pyrrol-1-yl phenyl ester and its conducting polymers BINGÖL, Bahar; GÜNER, Yusuf; Çırpan, Ali; Toppare, Levent Kamil (Informa UK Limited, 2005-08-01) Thiophen-3-yl acetic acid 4-pyrrol-1-yl phenyl ester (TAPE) monomer was synthesized via reaction of thiophen-3-yl acetyl chloride with 4-pyrrol-1-yl phenol. Homopolymers were achieved by using electrochemical and chemical polymerization techniques. Copolymers of TAPE with bithiophene or pyrrole were synthesized by potentiostatic electrochemical polymerization in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB) solvent-electrolyte couple. The chemical structures were confirmed by both Nuclear Magnet...
