PHYSICAL AND CHEMICAL PROPERTIES OF N2O

need for heating means that there is also an energy cost for producing the feedstockfor polymerization. Once we have a supply of the appropriate monomer (and any otherreagents that may be needed), we will have to pay to transport them to the plant wherethe polymer will be produced. Tha[r]

HistoryPolyethylene was first synthesized by the German chemist Hans von Pechmann who prepared it by accident in1898 while heating diazomethane. When his colleagues Eugen Bamberger and Friedrich Tschirner characterized thewhite, waxy, substance that he had created they recognized that it cont[r]
