ABSTRACT:  A series of new, highly conjugated diacetylenes, 4-ethynylstilbene derivatives, were synthesized and their polymerization was studied. None of them was found to undergo topochemical polymerization in the solid state but they readily polymerized in the molten state to give red transparent and amorphous polymers. All the polymers had an absorption maximum in the visible spectra around 500 nm, and FT-IR data showed the enyne structure of the polymer chain resulted from 1,4-addition.
