Using the same approach the new cycloproparenes 5 and 6 were obtained from the (2.2) paracyclophanetetraenes 7 and 8.* The silver-ion catalyzed polymerization of the dicycloproparenes 9 and 10 was also studied. This method has shown to be an alternative to the repetitive Diels-Alder reaction in the synthesis of ladder polymers. The ladder polymers 11 and 12 were obtained and characterized by IR, solid-state $\sp{13}$C-NMR and thermogravimetric analysis (TGA).* ftn*Please refer to the dissertation for diagrams.119 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
