Abstract
It has been proved experimentally that the condensation reaction between chain ends of poly(p-benzamide), (PBA), takes place and that the degree of polymerization (DP) of PBA increases by annealing in both the solid and liquid-crystalline states. A theoretical analysis of the reaction has shown that the DP distribution of the resultant polymer is again the most probable and the conversion of the reaction by weight is fairly high. The reactivity of PBA in the solid-crystalline state exceeded that in the liquid-crystalline state.
