There are many different extensions of the standard model of particle physics which result in modifications of the early universe expansion rate (the time -temperature relation). For example, additional particles will increase the energy density (at fixed temperature), resulting in a faster expansion. In such situations it is convenient to relate the extra energy density to that which would have been contributed by an additional neutrino with the ordinary weak interactions [19]. Just prior to e annihilation, this may be written as...

A. (2.0) Ratio Polymers. 1. High Acid Number Polyester Glycol Effects Figure 2 shows the polymerization viscosity-time-temperature relations for three (2.0) ratio thermoplastic poly(ester-urethane) elastomers. Numbers 1 and 2 were both made from the same reactant lots (I, II, and IX - Table I) at about the same reaction temperatures. 

Figure 4 shows the viscosity-time-temperature relations for three additional (2.0) ratio poly(ester-urethane) elastomers. These polymers, 6, 7, and 8 were all prepared from the same low acid number (0.15) PTAd (VII). And the antioxidant, Irganox 1010 (Ciba-Geigy), was added at 0.25 phr to the polymerization charges of these polymers. 

B. (3.0) Ratio Polymers Effect of Urethane Group Concentration. Figure 5 shows the polymerization viscosity-time-temperature relations for a (3.0 ratio) thermoplastic poly(ester-urethane) elastomer, Polymer 9. This polymer was made from reactants VI, IV, and X (Table I) the polyester glycol component being intermediate acid number PTAd (0.30).

Experience has shown that the time factor is more important than the temperature level in the time/temperature relation, and so the earlier emphasis on maintaining low operating temperatures in evaporators has shifted towards accurate control of low residence times and relatively higher operating temperatures. This has resulted not only in better products but also lower investment and operating costs.
