✦ Synopsis
Due to the tolerance of catalyst 7 in combination with the interesting properties of poly(DCPD), new filled or unfilled thermosets could be prepared, which should find novel applications in the field of electro casting, insulation, and tooling (among others) in the near future. Work to improve catalysts and polymer systems are ongoing.
Experimental Section
The ruthenium and osmium complexes were prepared according to literature procedures [ll]. NBE was purchased from Fluka, and DCPD (technical quality, 94%) from Shell and used as received. Viscosimetric measurements were performed on a home-built, real-time viscosimeter. Gel times were recorded on a Brookfield viscosimeter, DSCs on a Mettler DSC30 with a Mettler TCll controller, TGAs on a Mettler TG50 with a Mettler TCfOA controller, and surface roughness on a Form Talysurf S3C-50. Micro hardness was determined on a Fischerscope H100. I3C CP-MAS NMR spectra of a piece of poly(DCPD) that was tightly fitted into the spinner were recorded on a Bruker 400-MHz instrument with a MAS rate of 11 kHz and a pulse delay of 5 s (a pulse delay of 60 s gave an identical result).
