ResumoAbstract The structure of a free film of hydrolysed gamma-glycidoxypropyl-trimethoxy-silane is examined by various techniques. It is particulate rather than continuous in structure and there are residual hydroxy and methoxy groups. These hydroxyl groups are largely inaccessible to exchange with deuterium oxide. The structure suggested is mainly six-membered rings joined by short lengths of—SiO—chains and crosslinked by fusion of rings. The free hydroxyl groups on connected chains are protected by a spiral structure and probably from hydrogen bonds.
