since v1 log rS1 and v2 log rS2 . The values of v and u for a monomer are obtained from monomer reactivity ratios for copolymerization of that monomer with a series of reference monomers. A plot of the data according to Eq. 6-60a as [log r12 log r1S ] versus p1 yields a straight line whose slope is u2 and intercept on the y-axis is v2 . Table 6-8 shows values of the various parameters needed to calculate monomer reactivity ratios from Eqs. 6-60 and 6-62 [Jenkins and Jenkins, 1999]. The monomers in Table 6-8 are lined up in order of their u values. The Patterns of Reactivity scheme, like the Q e scheme, is an empirical scheme. Monomer reactivity ratios calculated by the patterns of reactivity scheme are generally closer to experimental values than those calculated by the Q e scheme, which supports the rationale of assigning different polarity values to a monomer and the radical derived from the monomer.

They are mainly rates of a traditional and stable sort Up to recently in the United States many types of interest rates fluctuated very sluggishly A 6% tradition lasted for at least two centuries Usury limits generally lasted unchanged until the 1960 s The rates on bank loans charged by banks far removed from money market centers and from Big Business were relatively stable for long periods Personal small loan rates rarely changed except with legislation The normal rates, which are frequently quoted for Mesopotamia, Greece, and Rome, appear for the most part to be rates paid for conventional short-term personal loans, usually but not always secured, and often secured on real estate A difference in rate for differences in term is rarely apparent from the data.

As business organizations of size and complexity did not exist, these were loans to persons or to partnerships, probably most often to meet personal needs but sometimes to finance trade or industry The quotations are generally for best credits This assertion by historians is supported by the risk rates which, when the law allowed, ran up far higher There also are pawnshop rates and loan shark rates which are far higher than the normal rates These latter, therefore, were probably well secured, either by land or movable valuables or by the established.

credit of a wealthy citizen If he desired, the Greek or Roman investor could get three to ten times these normal rates by taking the bottomry risk Finally, we have excellent evidence of great stability in these normal interest rates over known long periods of time This stability was due no doubt in part to tradition Even today tradition plays an important role in determining interest rates on loans far removed from a money market These ancient normal loans, if they are to be compared at all with modern loans, were probably most like modern personal loans made by small banks or by individuals The rate ten years ago in New England might have been 6%, as it was one hundred years earlier Western rates would have been higher but would rarely have been influenced by fluctuations in the Eastern money market.
