Consider the expression for reciprocal of average degree of polymerization, when styrene is polymerized with t-butyl hydroperoxide at 60ᵒC- 1/Xn = 0.6*10-4+10.0Rp+1.73*104 Rp2 Calculate the value of initiator transfer constant, if the monomer concentration is 8.35 mol/l and the value of the term kp2 fkd/kt= 3.29*10-9. Correct Answer 0.035

According to the expression for reciprocal of average degree of polymerization, we have 1/Xn = CM + (kt/kp2)(Rp/2) + CI(kt/kp2 fkd)(Rp2/3) Comparing the given equation, CI(kt/kp2 fkd)(Rp2/3) = 1.73*104 Rp2 CI = 1.73*104 * 3.29*10-9*(8.35)3 CI = 0.035.
