## Abstract Four titanium silanolates Ti(OSiR~2~Rโฒ)~4~ (1, R = Ph, Rโฒ = ^t^Bu; 2, R = Rโฒ = Ph; 3, R = Rโฒ = ^i^Pr; 4, R = Me, Rโฒ = ^t^Bu) were synthesised starting from Ti(O^i^Pr)~4~ and the corresponding silanol, and their thermally induced decomposition was studied. Colourless single crystals of T
New materials with higher thermal stability have been prepared by polycondensation of urea, form aldehyde and methacrylonitrile or furfuryl alcohol in the presence of titanium (IV) oxide as coupling agent. Their structures were confirmed by Fourier transform infrared spectroscopy. Thermal behaviour
## Abstract The synthesis of some novel ABA block copolymers is reported. The block A is a PPO while the block B is a random copoly(aryl ether sulfone), synthesized with three different molecular weights. The block copolymers were obtained by a two step procedure consisting on the functionalization
