Dilatometry is the technique most often used for studying the kinetics of polymerization by following the volume change which accompanies polymer formation. In this work, the kinetics of the ring-opening bulk polymerization of ε-caprolactone at 140 ℃ using 0.1 mol% stannous hexoxide as a novel initiator were studied. After a prolonged induction period, the results showed a close adherence to first-order kinetics with respect to monomer with a first-order rate constant, k_1, of 4.00×10^<-2> min^<-1>.
