Question

A sample of polystyrene prepared by bulk polymerization at 60 \deg C using radioactive (14C) AIBN as initiator was found to have Mn =1000 kg mol-1 and a radioactivity of 6 x 103 counts s-1g-1.Given that the AIBN has a radioactivity of 6x109 counts s-1 mol-1 , determine the mode of termination which operated in the preparation of polystyrene sample.

Step 1

To find the amount of AIBN, we can use the radioactivity of the AIBN and the radioactivity of the polystyrene sample. The radioactivity of AIBN is given as 6 x 10^9 counts s^-1 mol^-1. Show more…
