a For a new monomer, 40% conversion is obtained in 300 min when free-radically polymerized in homogeneous solution with a thermal initiator. How long will it be needed for 40% conversion in another run at the same temperature yet with five-fold initial initiator concentration? Assumption: steady-state free radical polymerization with the same rate constants. (Hint: Do the approximation by using Taylor series expansion ex = 1 + x1 + 2! x2 +...) .2
