Carbanionic polymer chains that contain polyene mer can be coupled after being reacted to include, at their respective termini, at least one, and preferably one, unit that is the radical of a cyclic polysiloxane. The coupled polymers are useful in preparing rubber compounds from which vulcanizates are made.
