A 0.1M solution of norbornene in nitrogen-sparged methylene chloride was added via syringe to the clean Schlenk flask containing initiator wafers from the previous section. The polymerization was allowed to proceed for 30 minutes at room temperature. After this time, the monomer solution was removed via syringe and replaced with 1M vinyl-containing chaintransfer agent solution in airfree methylene chloride (Scheme 1) being allowed to react for 1 hour. The slides were removed after this time and washed with distilled methylene chloride.
