Abstract

Highlights: [•] Ti4O16H16 and Ti4O14H12 clusters represent clean (001) and (100) anatase facets. [•] DMMP was adsorbed on clean, hydroxylated and hydrated clusters. [•] Destruction of DMMP is possible only on hydroxylated and hydrated surfaces. [•] Destruction of DMMP results in adsorbed methyl methylphosphonic acid and methanol. [ABSTRACT FROM AUTHOR]

Abstract

Long chain aliphatic ester, isopropyl myristate, was synthesized using energy efficient microwave irradiation technique. The iso propyl myristate forms complexes with titanium tetrachloride in different mole ratios. The nature of chemical bonding between the titanium and the ester functionality was investigated by FTIR and NMR spectroscopy. The performance of synthesized complexes with methylalumoxane as co-catalyst for ethylene polymerization was found to depend on the nature of complex and polymerization parameters. Molecular weight and thermal characteristics of polyethylene was also investigated. [ABSTRACT FROM AUTHOR]
