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 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 کاملKinetic equations for thermal degradation of polymers
Kinetic equations are analyzed for thermal degradation of polymers. The governing relations are based on the fragmentation–annihilation concept. Explicit solutions to these equations are derived in two particular cases of interest. For arbitrary values of adjustable parameters, the evolution of the number-average and mass-average molecular weights of polymers is analyzed numerically. Good agree...
متن کاملThermal and Oxidative Degradation of Polymers
In recent decades synthetic polymeric materials, because of their unique physical properties, have rapidly replaced more traditional materials such as steel and nonferrous metals, as well as natural polymeric materials such as wood, cotton, and natural rubber. However, one weak aspect of synthetic polymeric materials compared with steel and other metals is that these materials are combustible u...
متن کاملThe denaturation and degradation of stable enzymes at high temperatures.
Now that enzymes are available that are stable above 100 degrees C it is possible to investigate conformational stability at this temperature, and also the effect of high-temperature degradative reactions in functioning enzymes and the inter-relationship between degradation and denaturation. The conformational stability of proteins depends upon stabilizing forces arising from a large number of ...
