subsequently decreases at higher temperatures Termination is relatively unaffected at the lower temperatures but increases with temperature at the higher temperatures [Burrows and Crowe, 1962] Table 7-2 shows a decrease in the ultimate conversion of monomer to polymer for the oxetane polymerization as the reaction temperature is increased In this polymerization the effect appears to be due to thermal destruction of the initiator [Rose, 1956] The same trend is observed for most cyclic ether and acetal polymerizations but for a different reason Increased temperature usually decreases the conversion of monomer to polymer by a ceiling temperature effect The propagation depropagation equilibrium (Eq 7-41) is shifted to the left with increasing temperature The equilibrium monomer concentration increases with increasing temperature in accord with Eq 3-178 (keep in mind that H is negative) Figure 7-4 shows this effect for THF polymerization in bulk using benzene diazonium hexa uorophosphate as the initiator.

7-2b-6-b Thermodynamics of Polymerization The enthalpies and entropies of polymerization for various cyclic ethers and acetals are shown in Table 7-3 Data for formaldehyde and chloral are also included A comparison of the H and S values for alkenes, carbonyl monomers, and the cyclic monomers can be made from Tables 7-3 and 3-14 The H for the 3- and 4-membered cyclics are comparable to those for alkenes, and both are appreciably larger than the values for the two carbonyl monomers The conversion of a carbonyl p-bond to a s-bond is not as exothermic as the corresponding conversion of an alkene p-bond The H values for the larger-sized cyclic monomers are much lower than those for alkenes The S value is considerably smaller for most cyclic monomers compared to the alkenes and carbonyls.

Remember to either immediately hit the reset switch or the power switch or to quickly remove a battery upon the crashing of any bent instrument!

The cyclic monomers, having less degrees of freedom to begin with, have S values indicating that the loss in disorder on polymerization is less than for noncyclic monomers Ethylene oxide is an exception because of the highly strained nature of the 3-membered ring The S values for a few of the cyclic monomers, THF and 3,3-bis (chloromethyl)oxetane, are similar to the lowest values observed for alkene monomers..

was a 10% annuity In 1557 the Fuggers bought a similar 10% annuity secured by the revenues of Brabant and Flanders (320) One of the best German credits was the city of Nuremberg Nuremberg in 1540 1550 often borrowed on perpetual annuities at 5% When in 1553 there was an emergency caused by the need to build new walls quickly, the city floated an annuity loan at a rate as high as 12% By 1555 the rate was down to 10%; by 1558, 8%; 1561, 6%; and by 1565 it was back to 5% (321) In France, in 1522 perpetual annuities, called rentes, were floated free of coercion at 81 3% These were secured by the tax on wine They proved popular and more were sold at the same rate in 1536, 1537, and 1543 The rate was forcibly reduced to 4% in 1597.
