there were industrial booms and feverish activity. The fortunes of war swung from extreme to extreme and were often reflected in the market for the funds. After Waterloo, 1815, came the great peace, which lasted through the reigns of George IV, 1811 1830, William IV, 1830 1837, and Victoria, 1837 1901. The early years of this peace were eventful for English money and capital markets. A severe economic depression began in 1815 and brought falling commodity prices, falling interest rates, and unemployment. Its trough was in 1816. The note issue was thereafter reduced, interest rates rose briefly, and specie payments were resumed in 1821. A trend toward the construction of large factories then set in, based in part on the recent successful application of steam power to machinery. Imports of cotton increased fivefold by 1830. (426) The first railway was built in 1825, and in that year the repeal of the Bubble Act of 1720, which had restricted joint stock promotions, led to widespread projecting of new companies. In one month the shares of one company advanced 4000% in price. There were crises in 1825 and 1826 and a crash in 1827, which took with it 400 of the 600 new companies. (427) Severe depression lasted until 1832. However, capital promotions continued. At this time, the concept of preferred stock (preference shares)

13 C NMR of isotactic polypropene shows the main error is pairs of racemic dyads instead of isolated racemic dyads (Table 8-3) [Heatley et al, 1969; Resconi et al, 2000; Wolfsgruber et al, 1975] A stereoerror in the addition of a monomer molecule is immediately corrected when stereocontrol is by the chiral active site If stereocontrol was due to the propagating chain end, an error would continue to propagate in an isotactic manner to yield a polymer, referred to as an isotactic stereoblock, containing long isotactic all-R and all-S stereoblocks on each side of the error 2 13 C NMR of ethylene-propene copolymers of low ethylene content produced by initiators that yield isotactic polypropene shows that the isotactic propene units on each side of an ethylene unit have the same con guration (ie, all-R or all-S) [Zambelli et al, 1971, 1978, 1979].

For stereocontrol by the propagating chain end, the amount of polymer in which the polypropene blocks on either side of an ethylene unit have the same con guration would equal that in which the blocks have the opposite con guration 3 Statistical analysis of the stereochemical sequence distributions (Table 8-3 and Sec 8-16) also supports the enantiomorphic site control model Further insights into isoselective polymerization come from molecular mechanics studies showing that stereoselectivity is not due to direct interactions between monomer and the chiral active site [Corradini et al, 1979, 1982; Monaco et al, 2000] The effect of the chiral active site is indirect, at least for propene polymerization the mechanism is chiral orientation of the propagating polymer chain The chiral active site forces the propagating polymer chain to assume a chiral orientation, which results in discrimination between the two enantiofaces of the monomer.

Support for this mechanism comes from 13 C NMR examination of the con guration of the rst monomer unit inserted into the Ti active site [Ammendola R et al, 1986; Tritto et al, 1986; Zambelli et al, 1982a,b] The NMR analysis is enhanced by using 13 C-enriched alkyl groups in the group I III metal component There is some minimum.

was developed and proved useful in financing the forthcoming railway boom However, limited liability for stockholders did not become general until 1855 1862 In the 1830 s there was continued industrial expansion accompanied by speculation in United States land and United States companies, a brief start at a railway construction boom, and a further fall in interest rates Prosperity was interrupted by the effects of the American crisis of 1837 After a period of stagnation, the great railway construction boom of the 1840 s got under way Even the Bank of England bought railway debentures Interest rates declined further; 3% consols briefly crossed par, up over 100% since the lows of the Napoleonic Wars Another financial crisis in 1847 brought a sharp rise in interest rates and very severe bankruptcies.

It was followed by the revolutions of 1848 1849 on the continent of Europe, which had adverse effects on European markets In 1849 a period of heavy gold imports to London began, which arose from new discoveries in California and Australia Commodity prices rose Interest rates at first declined and then advanced Large sums were loaned abroad Britain financed railways in Europe and North America, and stock speculation became widespread British supremacy was now unquestioned The crisis of 1857 has been called the first worldwide crisis (428) and the first that was purely economic, without political or natural cause Many United States banks failed or suspended, and there was a run on the Bank of England A depression in 1858 1859 was followed by the stimulation and disturbances associated with the American Civil War.
