Room-temperature polymerisation of ethylene on a TiO2(anatase) surface; infrared spectroscopic evidence for an alkylidene–Ti4+ polymer end-group and for a ‘hydrogen-bonding’ type of interaction of CH bonds of the polymer chain with the oxide surface
Abstract
An infrared spectroscopic study of the spontaneous polymerization of ethylene on a sulphate-containing TiO2(anatase) sample shows evidence for an alkylidene surface end-group of the polymer and for substantial perturbation of CH2 groups of the polymer chain by interaction with the oxide surface.
