Summary

The configuration of maleic anhydride units in p-chlorostyrene/maleic anhydride copolymers prepared in methyl ethyl ketone at 50 ± 0.1°C and the corresponding comonomer unit sequence distributions were determined using the13C DEPT NMR sequence. It was found that the ratio ofcis (erythro) totrans (threo) configurations of maleic anhydride units increased with the degree of alternation of the comonomer units, reaching a constant value of approximately 0.73 when the comonomer units were almost completely alternating.
