Poly(octadecyl methacrylate)(P(n-OMA)) was synthesized. The sequence distribution of its stereoregularity has been studied ¹³C NMR spectra of by carbonyl, methyl and quaternary carbons. The contents of various stereosequences were determined and the rusults were in agreement with that obtained from FTIR spectra.The number average sequence lengths were determined in terms of ¹³C NMR spectra of triad sequence. The results suggest that the polymerization of alkyl methacylate is characterized by Bernoullian statistics.
