Disclosed is a crosslinked polysiloxane network comprising both residual Si-H linkages and a Lewis acid catalyst, wherein the network is derived from a linear hydridosiloxane, a branched hydridosiloxane, a cyclic hydridosiloxane or a mixture of a linear hydridosiloxane or branched hydridosiloxane and a cyclic hydridosiloxane. Disclosed also is a method to produce the crosslinked polysiloxane network, alternatively accompanied by a silane with aliphatic, aromatic, or cycloaliphatic substituents by reacting in the presence of an effective amount of a Lewis acid catalyst a linear hydridosiloxane, a branched hydridosiloxane, a cyclic hydridosiloxane or a mixture of a linear hydridosiloxane or branched hydridosiloxane and a cyclic hydridosiloxane. |
