AbstractThe interference function of liquid‐crystalline A/B‐block‐copolymers is given. The function is restricted to a one‐chain calculation, i.e. packing effects of neighbouring chains are neglected. It refers to fully elongated first‐order Markoff‐chains with A‐ and B‐sequences, the lengths of which are controlled by the transition probabilities pAA and pBB for A‐A and B‐B steps. Combinations of an A‐ and a B‐sequence each are considered as formal super‐comonomers which follow randomly after each other. Thus, a statistical super‐copolymer not of A‐ and B‐monomers but of A‐ and B‐sequences comes into existence, obeying the interference function as given by Blackwell, Biswas, and Bonart in an earlier paper. Whereas only the reference points of the A‐ and B‐comonomers were considered in the first part of the paper, also the atomistic structures of the comonomers are now taken into account. The result renders the possibility to analyse the chain statistics of liquid‐crystalline copolymers as will be shown in following papers.
