Pyrolysis-GC of High and Low Density Polyethylene
|Agilent Technologies|Applications
#58APPLICATIONS INFORMATION USING ADVANCED SAMPLE HANDLING TECHNOLOGYPyrolysis-GC of High and Low Density PolyethyleneAbundancePolyethylene, whether high density (HDPE) orC10low density (LDPE) is essentially a very longC14hydrocarbon molecule. Pyrolysis of PE produces shorter hydrocarbons, mostly normal alkanes, alkenes and dienes, which may...

Quantitation of Ethylene/Propylene Copolymers
|Agilent Technologies|Applications
#60APPLICATIONS INFORMATION USING ADVANCED SAMPLE HANDLING TECHNOLOGYQuantitation of Ethylene/Propylene CopolymersUnder pyrolysis conditions, polyolefins degradeby random scission to produce a chromatogramwith a characteristic repeating pattern of oligomeric fragments. Thus polyethylene (Figure 1,bottom) shows a pattern of normal hydrocarbons,while polypropylene (Figure 1,...
