Thin solid films of hydroxyethylcellulose/oligoether were obtained by a grafting reaction of HEC with diisocyanates, and were then characterized by DSC, FTIR, NMR and complex impedance techniques. The transparency of these films in the visible range

The effect of temperature on the ionic conductivity and the7Li NME line width of a polyether-polyurethane network containing lithium perchlorate was studied. A treatment of the results based on free-volume principles yielded a linear correlation betw

Examination of the quantitative correlation between the ionic conductivity and the dynamic mechanical properties of cross-linked polyether networks filled with an inorganic salt supports the assumption that mobile ions and chains segments need the sa

The ionic conductivity of polyoxyethylene- and polyoxypropylene-polyurethane networks containing sodium tetraphenylborate was studied as a function of temperature and salt concentration. The results can be rationalised in terms of free volume conside

A brief kinetic study is reported of the polymerisation of ethylene catalysed by four aluminium-titanium chloro-organic complexes, three of which are new. These systems proved efficient both in terms of polymerisation rate and of the linearity of the
