Hamer: Free Radical Polymerizations for Narrow Polydispersity Resins: Electron Spin Resonance Studies of the Kinetics and Mechanism. Volume 26, Number 20, September 27,1993, pp 5316-5320. Corrected versions of eqs 15,17, and 18 from p 5318 are shown: dP/dt = -kLPT + k,RM

(15)

dP/dt = kp,IoT + 2 k d 0 - kLPT

Line 2 of the first paragraph, and line 1 of the second paragraph on p 5319, should read ...the magnitude of (T - TO) ... Structure 1 on p 5317 should be as shown:
