The LDPE is composed of 4,000-40,000 carbon atoms, with many short branches. Two basic processes used for the production of low density polyethylene: stirred autoclave or tubular routes. The tubular reactor has been gaining preference over the autoclave route due to its higher ethylene conversion rates.
