Thermal Degradation of Polymers at High Temperatures
Work on thermal ~egradation of poly mers has prev iously been carried out aL lempC'mt ures up to about 500 G. In the present work the range has been extend cd to 850 0 C. Polystyrene was pyrolyzed in a vacuum and also in helium at atmos pheric pressure at 3620 and at 850 0 C. Analysis of t he volatile products indicates that higher temperatures a nd hi~her. pressures cause a greater fragmen tat...
متن کاملErratum: Thermal Expansion of Platinum and Platinum-Rhodium Alloys
Erratum: Equation (22) contains an error. It should read 100 ɛ(t, 0 °C) = 8.79 × 10 −4 t + 0.805 × 10 −7 t 2. (22) Also, the data presented in Table 12 under the column Day and Sosman Eq. (22) should be evaluated by using the corrected Eq. (22) above.
متن کاملThermal behavior of ethylene/1-octene copolymer fractions at high temperatures: Effect of hexyl branch content
In this work, the effect of hexyl branch content on thermal behavior of a fractionated ethylene/1-octene copolymer with emphasis on high temperatures was investigated. The ethylene/1-octene copolymer was carefully fractionated to different fractions with homogenous hexyl branch (HB) content by preparative temperature rising elution fractionation (P-TREF) method. The P-TREF fractions were therma...
متن کاملHigh Temperature Mechanical Properties of the Platinum Group Metals ELASTIC PROPERTIES OF PLATINUM, RHODIUM AND IRIDIUM AND THEIR ALLOYS AT HIGH TEMPERATURES
The platinum group metals are well suited for use at extremely high temperatures under mechanical loads and simultaneous corrosive attack. They have high melting points, excellent chemical stability and are highly resistant to oxidation. When using these materials in the design of components it is necessary to have data available on their elastic properties as a function of temperature. In this...
متن کاملThermal properties of iron at high pressures and temperatures.
We investigate the thermoelastic properties of close-packed phases of iron at pressures up to 400 GPa and temperature to 6000 K using a tight-binding total-energy method and the cell model of the vibrational partition function. The calculated properties are in good agreement with available static and shock-wave experimental measurements. The compressional behavior of a number of thermoelastic p...
