WebWhen ethylene was introduced to the precipitate along with an inert solvent, polyethylene with a high molecular and very little branching was formed. This polymerization took place at atmospheric pressure and 100°Celsius. How did this polymerization occur? The question is still debated today. WebThe first industrially useful synthesis of polyethylene via the high-pressure polymerization of ethylene gas was developed in 1933–35 and commercialized in 1939. This yielded a low-density polyethylene (LDPE) that was thermally processable and suitable for many applications, for example, tubing.
