Compression, supramolecular organization and free radical polymerization of ethylene gas
At low pressure, ethylene gas consists of single translating and rotating molecules and behaves as an ideal gas. With decrease of free volume by compression, various rotating supramolecular particles are formed, which require less space for the movement: molecular pairs, bimolecules and oligomolecules. The appearance of a new kind of particles is manifested as a phase transition of the second o...
متن کاملSurface-initiated Atom Transfer Radical Polymerization and Solution Intercalation Methods for Preparation of Cellulose-G-PS-G-PAN/MMT Bionanocomposite
Cellulose was modified by polystyrene (PS) and polyacrylonitrile (PAN) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method. For this purpose, first, the graft polymerization of styrene (St) onto cellulose fibers was performed by using suspension polymerization and ...
متن کاملNitroxide-Mediated Radical Polymerization of Styrene Initiated from the Surface of Titanium Oxide Nanoparticles
Titanium dioxide (TiO2) nanoparticles, with an average size of about 45 nm, were encapsulated by polystyrene using in situ nitroxide mediated radical polymerization in the presence of 3-aminopropyl triethoxy silane (APTES) as a coupling agent and 2, 2, 6, 6-tetramethylpiperidinyl-1-oxy as a initiator. First, the initiator for NMRP was covalently bonded onto the surface of Titanium dioxide na...
متن کاملSynthesis and identification of polystyrene via conventional and controlled radical polymerization methods: Effect of temperature, initiator and transfer agent on molecular weight and reaction rate
Polystyrene (PSt) has been known as one of the important polymers with a wide range of applications. Ability to synthesize PSt with different but predictable molecular weights for various applications is very important in the laboratories and industries. In this study, using various simple and inexpensive techniques with only free radical mechanism, it was tried to synthesize PSt with different...
متن کاملSynthesis of Polyvinyltetrazole by Combination of Free Radical Polymerization and Click Chemistry for Adsorption of Pb (II) in Aqueous Solution
Polyvinyltetrazole (PVT) is produced from acrylonitrile (AN) monomer by using free-radicalpolymerization and Click Chemistry methods. The resulting polymer with a broad range of tetrazolegroup contents was conveniently synthesized through [3+ 2] azide-nitrile cycloaddition reaction ofnitrile-containing polymer with sodium azide in DMF. The prepared PVT was characterized by13CN...
