In polyisocyanates composed only of randomly distributed (R) and (S) units, the chiral optical properties of the polymer are far out of proportion to the enantiomeric excess of the monomers. This highly disproportionate relationship, which arises from a majority-rule effect among these enantiomeric units on the helical sense of the backbone, is unaffected, within certain limits, by the overwhelming presence of achiral units randomly distributed along the chain. This exptl. result can be explained quant. by an anal. based on the one-dimensional random-field Ising model, which shows that dilution of the chiral units with achiral units increases the helical domain size in a manner that compensates for the dilution In qual. terms, since the random-field domain size is limited by the objection of the minority units to the helical sense dictated by the majority units, dilution of this objection acts to increase the domain size. As long as this domain size is not limited by the chain length or by thermal fluctuations, the achiral dilution will not reduce the optical activity of the polymer.
