ABSTRACT:
A crosslinked organosilicon polymer or crosslinkable organosilicon prepolymer comprising alternating (a) polycyclic polyene residues and (b) polysiloxane/siloxysilane residues linked through carbon to silicon bonds, wherein the polycyclic polyene residues are derived from polycyclic polyenes having at least two non-aromatic carbon-carbon double bonds in their rings and the polysiloxane/siloxysilane residues are derived from (i) cyclic polysiloxanes or tetrahedral siloxysilanes and (ii) linear, .tbd.SiH terminated polysiloxanes.
