On the basis of the Randall calculations, the isotactic
sequence length and the syndiotactic sequence length in
a polymer chain are defined as follows . . . :
isotactic sequence length = n = 1 + 2mm/mr (I)
iso
syndiotactic sequence length = n = 1 + 2rr/mr (II)
syn
Based on equations (I) and (II) n and n can beiso syn
calculated from the data obtained from the triad analysis
of the C-NMR polymer spectra (relative amounts of the13
triads mm, mr and rr with mm + mr + rr = 100% or
normalized
mm + mr + rr = 1).
Using equations (I) and (II) above and triad analyses of
the C-13 NMR spectra pentad compositions for the polymers of
