We present a theory of the first-order transition to the metallic state in polyacetylene in terms of a crossover from a lattice of charged solitons to a regular array of polaronlike distortions. The polaronic metal is shown to have a strong indirect attractive interaction, U*{}-2{Δ}/3, between electrons in the half-filled, narrow, polaron subband within the Peierls energy gap (Eg=2{Δ}).
