摘要：

Using proton and deuterium NMR we show that in polydisperse nematic polyesters with mesogenic units in the main chain: (i) in the nematic-isotropic biphase, the nematic phase is enriched with the longest species and (ii) in the nematic phase itself there is additional segregation by molecular mass into nematic domains.
