    • In order to get absolute mKs one needs to establish both the dependence of the birefringence on the 4-BrS concentration (reported here in terms of Kerr constants, i.e, the slopes in Fig. 2) and the variation of PBrxS solution dielectric constants and refractive indices with the 4-BrS concentration. Because all three terms in the expression of mKs are additive (references [30,31, we neglected any differences in solution dielectric constants and refractive indices (because dielectric constants and refractive indices should only depend on comonomer composition and not comonomer sequence) and instead worked with ratios of the experimental birefringences to learn the effects of comonomer sequence at constant comonomer composition
