Is Polyethylene a liquid, Gas, or Solid?
Polyethylene has the chemical formula (C2H4)n. It is made by utilizing a metal-compound catalyst (or one supported on a carrier) to break the double bonds in the ethylene molecules, linking the monomers to create a long-chain polymer.
The gas ethylene, which serves as the monomer, has a melting point of -169.2 C and a boiling point of -103.7 C.
The melting temperature of the solid polymer PE is determined by its chain length or n value, and it ranges from 105 to 115 C for low-density polymers to up to 180 C for high-density polymers.
I suppose PE can claim to have a little liquid attribute as plastics do exhibit both elastic and irreversible plastic flow qualities when subjected to sustained loads.
