For polymers, a prefix denoting a type of molecular structure. For some unsaturated carbon chain atoms within a mer unit, a side atom or group may be situated on one side of the chain or directly opposite at a 180 rotation position. In a cis structure, two such side groups within the same mer reside on the same side (e.g., cis-isoprene).
