Chain length distribution

Chain length distribution Crucial in the derivation of the CLD is the chance on formation of an i-mer chance on propagation:. thus: chance on chain stop: 1-p During the growth of a single chain p is constant. disproportionation mol fraction i-mer :. mass fraction i-mer :. which yields:.
