Abstract
PolyethyleneIt has been known for many years that ethylene could be polymerized, but until 1936, when a new process involving high pressures was devised in England, only liquid and semiliquid polymers were obtained. Polyethylene was first employed experimentally in the United States in 1941.57 The commercial use of polyethylene began here in 1943, when it was first produced in quantity.1 Ethylene has a simple chemical structure, and polyethylene, which is a polymer of ethylene, is —theoretically, at least — the simplest structure in which a chain polymer can exist. It consists of carbon atoms joined in a chain, each . . .
