contour length [obsolete]

in polymers
The maximum end-to-end distance of a linear polymer chain. For a single-strand polymer molecule, this usually means the end-to-end distance of the chain extended to the all-transconformation. For chains with complex structure, only an approximate value of the contour length may be accessible. The sum of the lengths of all skeletal bonds of a single-strand polymer molecule is occasionally termed 'contour length'. This use of this term is discouraged.
