Polymerization of allyl cyanide was carried out by radiation and chemical catalysis. Polymers obtained by γ-rays under various conditions such as in bulk and in the presence of either air or 0.1 mol% ZnCl2 were oily or solid dark-brown products with molecular weights up to 1.4 × 104. The polymers obtained by n-BuLi was a pale-yellow solid, insoluble in common organic solvents and water. No polymer was obtained with BF3O(C2H5)2. The mechanism of polymerization was shown by infra-red investigation to be different for radiation and catalyst polymerization. The relation between intrinsic viscosity and number-average molecular weight was found to be [η] = 4.4 × 10−4M0.51n. The dipole moment ratio D∞ of poly(allyl cyanide) in 1,4-dioxane was measured. The relatively large value of D∞ shows that the polymer chain is not very rigid. A conformational change was observed at 40°C based on dipole moment measurements.

Polymerization of propylene oxide and copolymerization of carbon disulphide and propylene oxide with xanthate salts
Aksoy, S.; Balkan, M.; Alyürük, K. (Elsevier BV, 1989-1)
Anionic polymerization of propylene oxide (PO) using several xanthate salts was studied. Low molecular weight oily polymers with variable sulphur content were obtained by using either potassium ethyl xanthate or potassium benzyl xanthate. The highest attainable conversion of PO was limited to ca 10%. The polymerization was accompanied by formation and precipitation of a by-product salt. In the presence of CS2, an oily copolymer with about 40% sulphur was obtained from the above mixtures. In reaction systems...
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...
Preparation of conductive polybenzoxazines by oxidative polymerization
Kiskan, Baris; Yagci, Yusuf; Sahmetlioglu, Ertugrul; Toppare, Levent Kamil (Wiley, 2007-03-15)
precursors were prepared by oxidative polymerization 3-phenyl-3,4-dihydro-2H-benzo[e][1,3] oxazine (P-a) alone and in the presence of thiophene (Th) with ceric ammonium nitrate in acetonitrile. The structure of the precursors was confirmed by FTIR, H-1 NMR, and DSC measurements, indicating the presence of a cyclic benzoxazine structure, together with small but varying amount of a ring opened phenolic structure. The resulting polymers exhibit conductivities around 10(-2) S cm(-1) and undergo thermal curing a...
Polymerization of 1,2-epoxy-4-epoxyethylcyclohexane
Usanmaz, Ali; Asaid, Adel (Wiley, 1986-12)
Radiation‐induced polymerization of 1,2‐epoxy‐4‐epoxyethylcyclohexane (EECH) has been carried out at different temperatures in solid and liquid states. Activation energy was calculated from Arrhenius plot and ionic mechanism was proposed. Molecular weights for some polymer samples were determined by cryscopic method and compared with their intrinsic viscosities. Cationic polymerization of EECH initiated by BF3 · O(C2H5)2 and anionic polymerization initiated by NaOH are also studied. Two epoxy rings can be o...
Monomer-bound ion pairs in the stereoregular polymerization of propylene oxide by the Pruitt-Baggett catalyst
Aksoy, S.; Altinok, H.; Tümtürk, H.; Alyürük, K. (Elsevier BV, 1990-6)
The Pruitt-Baggett adduct (PBA) (MW = 438 g mol−1) that formed from the reaction of FeCl3 with propylene oxide (PO) was hydrolysed in diethyl ether (ether) solutions at different molar ratios. The hydrolysates (), which were insoluble in ether, could be converted into catalytically active form () by a thermal treatment. was soluble in etheric solvents and in pyridine. These solutions, in contrast to PBA and , were electrical conductors. Profound differences in the electrical conductivity of was observed ...
