Kinetic Chain Length v is defined as the number of molecules reacting with a reactive centre from its formation to its termination.
V=R[> = Be = kp [M][M~] = kp [M][M‘]
Rt Ri 2kt [M ]2 2fkd[l]
thus;
kp[M] _ kg[M]2 2kt [M*] 2kt Rp
So that the Kinetic Chain Length is inversely proportional to the rate of polymerisation.
