Evidence of coordinative chain transfer polymerization of isoprene using iron iminopyridine/ZnEt₂ catalytic systems

analysis of ruin probability for insurance companies using markov chain

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...

End-capped Oligomers of Ethylene, Olefins and Dienes, by means of Coordinative Chain Transfer Polymerization using Rare Earth Catalysts

Iron-catalyzed polymerization of isoprene and other 1,3-dienes.

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Polymerization of Isoprene by Using Benzyl Diethyldithiocarbamate as an Iniferter

The polymerization of isoprene through the use of benzyl N,N-diethyldithiocarbamate (BDC) as an iniferter was investigated. The monomer concentration used was kept constant at 2.8 mol/L while the BDC concentration was varied. The polymer product was characterized by Fourier Transform Infrared Spectroscopy (FTIR), Proton Magnetic Resonance (H-NMR), and Differential Scanning Calorimetry (DSC) and...
