Claim 5:
6. The method as claimed in claim 5, wherein
the one or more precursors comprise:
a first polysiloxane precursor having as the at least one first reactive group at least two groups each including an unsaturated bond and each chosen from the group consisting of alkyne, alkene, vinyl, aldehyde, ketone and imine, and
a second polysiloxane precursor having at least two hydrosilane groups, and

the at least one second reactive group is chosen from the group consisting of alkyne, alkene, vinyl, aldehyde, ketone, imine and hydrosilane; and, the mixture further comprises:
a hydrosilylation catalyst for catalysing an addition of an hydrosilane group across the unsaturated bond; and wherein the polymerisation includes causing the addition of the hydrosilane groups across the unsaturated bonds to therewith form the organic polymeric bulk portion.
