"Small-angle X-ray scattering investigation of the cluster distribution in inorganic-organic hybrid polymers prepared from organically substituted metal oxide clusters";
Comptes Rendus Chimie, 7 (2004), 495 - 502.

Hybrid polymers prepared by radical polymerisation of the tetranuclear metal oxide clusters Ta₄O₄(OEt)₈(OMc)₄ (OMc = methacrylate) with styrene, or of Ta₄O₄(OEt)₈(OMc)₄, Ti₄O₂(OEt)₆(OMc)₆ and Hf₄O₄(OMc)₁₂ with methyl methacrylate were investigated by small-angle X-ray scattering (SAXS) to elucidate the distribution of the clusters in the polymer. Besides the random distribution of the clusters, three different types of aggregation behaviour were observed with two different inter-cluster distances each: the shorter distance being constant when the cluster portion in the polymer was varied, the longer distance being constant or both distances being constant.
