    Notes: Macroporous sulfonated polystyrene ion exchange resin was reacted with elemental fluorine in a liquid-phase suspension reactor at low temperature. This method gave retention of the bulk structure of the resin bead and resulted in a space-selective distribution of fluorine across the resin bead cross-section, as determined using 19F secondary ion mass spectroscopy (LMI-SIMS). The polymer modification was additionally characterized using x-ray photoelectron spectroscopy, photoacoustic IR spectrophotometry, 19F, and 13C MAS NMR spectrometry, and mercury porosimetry. © 1994 John Wiley & Sons, Inc.

    Notes: This paper describes the ring-opening methathesis polymerization of homopolymers and copolymers of exo- and endo-2-cyanobicyclo[2.2.1]hept-5-ene (norbornenenitrile) in solution. Polymerization kinetics were followed via 1H NMR spectroscopy in real time while the final polymer microstructure was determined via 13C NMR. While pure endo monomer does not polymerize readily, it copolymerizes with exo monomer, rapidly and to high conversions. The structure of the copolymer appears to be quite similar to that of exo homopolymer. We conclude that exo monomer adds directly to either exo or endo, while endo-endo addition is sterically hindered.
