Structural characteristics and gas permeation properties of polynorbornenes wit...
Zhao, Chun-tian; Ribeiro, M. do Rosário; Pinho, M. N. de; Subrahmanyam, V. S.; Gil, C. L.; Lima, A. P. dePolynorbornenes of different molecular weights were synthesised by addition polymerisation, using a nickel based catalyst. This polymerisation route leads to amorphous polymers that were shown to display unique properties: high glass transition temperature, rigid random coil conformation, and dense packing in the amorphous state. Gas permeation membranes were prepared from these addition type non-substituted po...
