Abstract in another language

The vinyl-type homo- and copolymerization of 9-norborn-5-en-2yl-nonane acid ethyl ester and 2-hexyl-5-norbornen was investigated. Both monomers were polymerized using di-mu-chlorobis(6-methoxybicyclo[2.2.1]hept-2-ene-endo-5 sigma,2 pi)palladium(II) and AgSbF(6) as catalysts. Poly(2-hexyl-5-norbornene) is soluble in common organic solvents and has a T(g) of 252 degrees C. Poly(9-norborn-5-en-2yl-nonane acid ethyl ester) shows swelling in solvents like THF, chlorobenzene or chloroform and has a T(g) of 136 degrees C. The solubility of the copolymers depends on the amount of 9-norborn-5-en-2yl-nonane acid ethyl ester. E-modulus measurements of copolymers with different amounts of ester showed an increase of flexibility when increasing the content of 9-norborn-5-en-2yl-nonane acid ethyl ester in the copolymer.
