    Notes: Metathesis ring opening polymerization has been used to copolymerize norbornene and 7,8-bis(trifluoromethyl)tricyclo[4,2,2,02,5]deca-3,7,9-triene. Subsequent thermal elimination of the precursor copolymers yielded acetylene-norbornene copolymers. The undoped copolymers were found to have electrical conductivity, spin concentration, and EPR linewidths which vary with composition. The location of the trans-C—H out-of-plane vibration, however, was invariant at 1010cm-1 indicating that conjugation length of n 〉 4 are present even at 40% acetylene content in the copolymer. The copolymers containing 79 mol % of acetylene units attained a doped conductivity of 0.02 S/cm with a dopant concentration of 6 mol % of I3- per sp2 carbon.

    Description / Table of Contents: Die beim thermischen Abbau von Poly(4-methyl-1,3-dioxolan) gebildeten Verbindungen wurden durch gekoppelte Gaschromatographie und Massenspektrometrie analysiert. Zahlreiche Abbauprodukte auf Basis von Aldehyden, Ketonen, Alkoholen, Ethern und sauerstoffhaltigen cyclischen Verbindungen wurden erhalten. Die änderung der relativen Molekülmasse während des Abbaus wurde gemessen. Die Aktivierungsenergie für den Abbau des Polymers wurde bestimmt.
    Notes: The products of degradation of poly(4-methyl-1,3-dioxolane) have been analyzed by combined gas chromatographymass spectroscopy. Numerous degradation products were observed based on aldehydes, ketones, alcohols, ethers, and oxygenated cyclic compounds. The changes of molecular weight during the degradation were determined. The activation energy of the degradation of the polymer was measured.
