Dear all....
For a NMR measurement I need a good solvent for a crosslinked silicone
rubber.
Any recommendations available ?
Thanks....Guenter |

Toluene is a good first choice, or heptane. They should work at room
temp given time. Or maybe some heat to get things going, but things
should stay afloat after cooling back to RT.
Si-29?

By definition, crosslinked means not fusible or soluble. Best you can
hope for is swelling with the solvent. System mentioned below probably
breaks cross links:
