The solid-state polymerization of 1,4-disubstituted trans, trans-butadienes has been investigated in perovskite-type layer structures and lipid layer structures. X-ray structure analyses of the complex salts as polymer and as monomer are presented. Polymerization of 1 causes the formation of an erythro-diisotactic 1'4-trans-polybutadiene in a lattice controlled reaction. Crystals of 2 exhibit a Jahn-Teller-distortion of the CuCl6 octahedra, which forces the monomer units into a packing geometry highly unfavourable for a solid state reaction. Long chain butadienes such as 2,4-hexadienoic acid n-octadecylester (3) and 6-(n-octadecanoylamino)-2,4-hexadienoic acid (4) polymerize upon exposure to UV-and γ-irradiation. Studies by infrared and 13C-NMR-spectroscopy indicate the formation of 1,4-trans-polymers in the crystalline state as well as in Langmuir-Elodgett-multilayers.
