We report recent results on a search for exclusive hadronic decays of charmonium states (χcJ ) decaying into vector-vector meson (χc → V V ), using a sample of 3 million ψ(2S) recorded with the CLEO detector. We present branching ratio measurements for χc → V V , which include the decays χc → ωω and χc → φφ. Branching ratios for χc1 → ωω and χc1 → φφ are measured for the first time.
