n-Butyl isocyanate (nBIC) was polymerized in bulk by the Pruitt-Baggett adduct (PBA) at -23, 0.0, and 25.0-degrees-C. Polymerization was accompanied by trimerization to the cyclic isocyanurates at all temperatures. Spectroscopic evidences supported the nylon-1 structure for both trimer and polymer. The polymer /trimer ratio and the molecular weight of produced polymers were found to increase with decreasing temperature. The Pruitt-Baggett catalyst (PBC), which is the reaction product of (PBA + H2O) system, also polymerized nBIC, but with a relatively slower rate. In aromatic and etheric solutions, nBIC was only trimerized by PBA. Copolymerization of nBIC with propylene oxide by PBA and PBC failed. Some selected monoisocyanates were also polymerized by PBA.

ELECTROINITIATED COPOLYMERIZATION OF INDENE WITH BETA-METHOXYSTYRENE Akbulut, Ural; HACIOGLU, B; Toppare, Levent Kamil (Elsevier BV, 1990-07-01) Electroinitiated copolymerization of indene with β-methoxystyrene was carried out at 0°C and five different potentials. Monomer consumption was studied by cyclic voltammetry. It is known that, when the difference between oxidation potentials of two monomers is large, polymerization potential affects copolymer composition. In the present study indene and β-methoxystyrene were selected because their oxidation potentials are almost equal, ca. + 1.40 V. The effect of polymerization potential on copolymer compos...
Dibenzophenazine Derivatives as Visible Photosensitizers for Diaryliodonium Salts Bulut, Umut; Kolay, Merve; Tarkuc, Simge; Toppare, Levent Kamil (Wiley, 2011-08-01) The use of two dibenzo[a,c]phenazine derivatives, 10,13-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)dibenzo[a,c]phenazine and 10,13-bis(4-hexylthiophen-2-yl)dibenzo[a,c]phenazine are reported as photosensitizers for diaryliodonium salt photoinitiators. Novel dyes based on the dibenzo[a,c]phenazine skeleton are shown to be efficient in carrying out the cationic photopolymerizations. Representative examples of different types of monomers including epoxide, and vinyl monomers are polymerized in the presence o...
Polymerization of propylene oxide by the Pruitt-Baggett catalyst Çolak, Nureddin; Alyürük, Kemal (Elsevier BV, 1989-9) The Pruitt-Baggett adduct (PBA) which formed from the reaction of FeCl3 with propylene oxide (PO) was hydrolysed in diethyl ether (ether) solutions at different mole ratios. Although the hydrolysates were insoluble in ether they could be converted into PO-soluble form (PBC) by a thermal treatment providing that the r value was kept smaller or equal to unity. PBC polymerized PO concurrently into a mixture of high molecular weight crystalline polymer with low molecular weight non-crystallizable oligomers. Th...
Polymerization of allyl alcohol by radiation to obtain microencapsulated structure Usanmaz, Ali; Sarıcılar Zengin, Süreyya (Springer Science and Business Media LLC, 1989-4) Allyl alcohol was polymerized by radiation under various conditions. The limiting conversions were about 30% in bulk, 35% when containing 0.03 mole fraction AlCl3 and 50% when water was contained at 27% (v/v). Irradiation was done with Co-60 gamma rays at room temperature and under vacuum. The presence of oxygen did not cause any change in the reaction rate. Molecular weights were determined by viscosity and cryoscopic methods. K and α values were found to be 3.57×10−4 and 0.62 for solutions in methanol at ...
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...
