Polyethylene
8/30/2008
“Polyethylene or polythene (IUPAC
name poly(methylene)) is a thermoplastic commodity heavily used in consumer
products (notably the plastic shopping bag). Over 60 million tons of the
material are produced worldwide every year.”

“Polyethylene is a polymer consisting of long chains of the monomer ethylene (IUPAC
name ethene). The recommended scientific name polyethene is
systematically derived from the scientific name of the monomer. In certain
circumstances it is useful to use a structure–based nomenclature. In such cases
IUPAC recommends poly(methylene). (poly(methanediyl) is an non-preferred
alternative). The difference in names between the two systems is due to the
opening up of the monomer's double bond upon polymerisation.”

Notes
“In the polymer industry the name is sometimes shortened to
PE in a manner similar to that by which other polymers like polypropylene
and polystyrene are shortened to PP and PS respectively. In the United Kingdom
the polymer is commonly called polythene, although this is not recognized
scientifically.”
