Summary The methylene carbon resonance patterns of partially epimerized isotactic polystyrenes were measured and interpreted in terms of tetrad and hexad stereosequence distributions that were calculated by Monte Carlo simulation of the epimerization process. Empirical rules were developed for assigning hexad resonances. Calculated spectra based on these assignments and on the Monte Carlo results were in reasonably good agreement with experimental spectra. The resonances of mmtype methine carbons were noted to occur about 0.2 ppm downfield from other methine carbon resonances.
