Flory’s theory of stereochemical equilibrium in vinyl polymers is generalized. Equilibrium frequencies for stereochemical sequences of any length (m-ads) in chains of any length x can be obtained with the new formulation; the calculated frequency is averaged over the entire length of the chains. Some numerical results for sequences up to m= 5 (pentads) are presented, and it is demonstrated that the dyad distribution in vinyl chains at equilibrium does not follow any type of unidirectional statistics, eg, any order Markoff.
