Crystal orbital coupled-perturbed Hartree-Fock (CPHF) static and dynamic (S/D) polarizabilities were computed for polydiacetylene (PDA) and polybutatriene (PBT). The static CPHF/6-31G second-order hyperpolarizability of PBT was found to be 67 times larger than that of PDA. It was shown from the calculations that a smaller S/D produced a larger polarizability and second-order hyperpolarizability of PDA.
