Novel photosensitizers are disclosed which are particularly useful in photopolymerizable organopolysiloxane and silicone resins. The photosensitizers are themselves organopolysiloxanes which contain at least one silicon-bonded benzophenone-containing radical. Synthesis methods are disclosed for preparing these photosensitizers which employ, as starting materials, an alkenyloxy-substituted benzophenone and a silicon compound containing at least one silicon-bonded hydrogen atom.
