WebFactors affecting chain packing. Introducing chain branching and unsaturation, particularly of cis double bonds, reduces ℓc and thus increases v / a0ℓc. Similar effects occur when the effective volume, v, of the chains is increased due to the penetration of organic molecules such as low MW alkanes into the chain regions.
