We explore the implications of the conservation law(s) and the corresponding"continuity equation(s)", resulting from the coupling between the positionaland the orientational order in main-chain polymer nematics, by showing that thevectorial and tensorial forms of these equations are in general not equivalentand can not be reduced to one another, but neither are they disjointalternatives. We analyze the relation between them and elucidate thefundamental role that the chain backfolding plays in the determination of theirrelative strength and importance. Finally, we show that the correct penaltypotential in the effective free energy, implementing these conservation laws,should actually connect both the tensorial and the vectorial constraints. Weshow that the consequences of the polymer chains connectivity for theirconsistent mesoscopic description are thus not only highly non-trivial but thatits proper implementation is absolutely crucial for a consistent coarse graineddescription of the main-chain polymer nematics.
