It is the most common notion with us that day by day purchasing power of our currency reduces on time line. It is a fact also. We find views and debate on the issue "Why and how it is so?" I also contemplated on it and I have tried to put my observations and out comes while pondering on the issue. On one part, it is tried to peep into the fetus of the money. On other side, it is tried to locate the foundation of money that determines the reliance of its purchasing power. The influence of parameters that determines the exchange ratio in any exchange process between commodity and money is also considered. It is revealed that human characteristics and overall health of social systems, efficient functioning of social institutions and ethical as well as moral values of members of the society projects grass root influence on determining the exchange value of money for any nation. It is to be noted that money has never a value, but it is evolved with human society where it has exchange value and an exchange value is never a value.

Five new copolyesters 3 ae were prepared by reacting P-(4-methoxy-3 methy1)phenylglutaconic acid dichloride (1 b) with diols 2ae. The polymers were characterized by IR and TG. All polymers were found to decompose in the range of -200 to =65O"C.

Some polyester and polyamide resins were prepared by condensing p(2-methoxy-5methylphenyl) glutaconic acid with diols and diamines. The polycondensates were characterized by IR, TG, DSC, VPO, and elemental analysis. Some polycondensates were found to be soluble in acetone, dimethylformamide, and dioxane. All polymers were found to decompose in the range of -200 to -600°C. Their softening points are in the range of -90 to -190°C. They are brown black in colour. The kinetics of decomposition were studied. The kinetic parameters were evaluated by the method of Broido. It is observed that the energy of activation of polycondensates depends upon the presence of diol and diamine components in the polymer. ZUSAMMENFASSUNG:Es wurden Polyester-und Polyamidharze durch Kondensation von fb(2-Methoxy-5-methylphenyl)glutaconslure mit Diolen und Diaminen hergestellt. Die Polykondensate wurden mit Hilfe von IR, TG, DSC, VPO und durch Elementaranalyse charakterisiert. Einige Polykondensate waren in Aceton, Dimethylformamid und Dioxan 16slich. Alle Polymeren zersetzten sich zwischen ux) und 600°C. Ihr Enveichungspunkt lag zwischen 90 und 19o"C, sie waren braunschwarz geflrbt. Die Kinetik der Zersetzung wurde untersucht. Die kinetischen Parameter sind nach der Methode von Broido ausgewertet worden. Es zeigte sich, daI3 die Aktivierungsenergie der Polykondensate von der Anwesenheit der Diol-und Diaminkomponenten im Polymeren abhlngt .

Someunsaturated polyamide resins were synthesized by condensing @2-ethoxy-5-methylphenyl) glutaconic acid with six diamines The polycondensates were characterized by IR. TG, DSC: VPO and elemental analysis. Most of the polymers were found to decomposi in the range of -190 to 6OO0C. They are brownblack in nature. The kinetics of decomposition was studied. The kinetic parameters were evaluated by the method of Broido. It was observed that the energy of acti~ration of polycondensates depends upon the presence cf diamine components in the polymer.
