Abstract
The polymerization of propylene oxide on the surface of thermoactivate d anatase has been studied by infrared spectroscopy, thermal gravimetr y, field ionization mass spectrometry, and quantum-chemical simulation . Data are given upon the dependence of the grafted oligomer mass on t he temperature of the preliminary treatment of anatase surface. The co ordination mechanism of the propylene oxide polymerization with the pa rticipation of Ti4+ ions of the TiO2 matrix is discussed.
