In the above equations and are used to indicate all acid or alcohol species in the reaction mixture (ie, monomer, dimer, trimer, , n-mer) Species I and II are shown in the form of their associated ion pairs since polymerization often takes place in organic media of low polarity (A ) is the negative counterion derived from the acid HA Polyesteri cations, like many other step polymerizations, are equilibrium reactions However, from the practical viewpoint of obtaining high yields of high-molecular-weight product such polymerizations are run in a manner so as to continuously shift the equilibrium in the direction of the polymer In the case of a polysteri cation this is easily accomplished by removal of the water that is a by-product of the reaction species II (Eq 2-14) Under these conditions the kinetics of polymerization can be handled by considering the reactions in Eqs.

2-13 and 2-14 to be irreversible (A consideration of the kinetics of a reversible step polymerization is given in Sec 2-4c) The rate of a step polymerization is conveniently expressed in terms of the concentrations of the reacting functional groups Thus the polyesteri cation can be experimentally followed by titrating for the unreacted carboxyl groups with a base The rate of polymerization Rp can then be expressed as the rate of disappearance of carboxyl groups d[COOH]/dt For the usual polyesteri cation, the polymerization rate is synonomous with the rate of formation of species II; that is, k4 is vanishingly small (since the reaction is run under conditions that drive Eqs 2-13 and 2-14 to the right), and k1 , k2 , and k5 are large compared to k3 .

even lower levels. Holland had first experienced such low rates in the seventeenth century, England in the early eighteenth century, and Europe generally in the mid-nineteenth century. Now Dutch finance crossed the Atlantic. The United States, with the Civil War behind it, was approaching the status of a great financial power in its own right. It no longer had to pay high interest rates for foreign capital. Commodity prices were falling here, as they were in Europe, and there was an enormous growth of capital investment. A de facto gold standard was established. While shortterm American interest rates continued their wild gyrations, occasionally soaring to high levels such as 186% in 1899, and declining to low levels such as 1% in the same year, long-term prime bond yields became stable and low in the European manner. This well-defined decline in bond yields dates from 1873 1875. The New England municipal average stood at 5.67% in 1873, at 4.15% in 1879, at 3.35% in 1889, and at a low of 3.07% in 1899. The railroad average stood at 6.50% high in 1873, at 4.66% in 1879 still well above municipal yields 3.48% by 1889 now close to municipal yields and hence thoroughly respectable and as low as 3.07% in 1899. This twenty-five-year bull bond market brought impressive capital gains only to those who were lucky enough to hold truly long-term bonds of high quality. High-coupon callable governments had been called away. Many railroad bonds had defaulted and many others had matured. Only a few high-grade bond issues had long enough redemption terms to permit the full benefit to investors from the dramatic decline in yields. Some examples of the change in yields and of market appreciation of corporate bonds are shown in the accompanying table:
