Poly ethene is produced from the monomer
WebCrude oil is a complex mixture of hydrocarbon molecules. The hydrocarbon molecules in crude oil are separated by fractional distillation. Fractional distillation. is used because … Polyethylene is classified by its density and branching. Its mechanical properties depend significantly on variables such as the extent and type of branching, the crystal structure, and the molecular weight. There are several types of polyethylene: • Ultra-high-molecular-weight polyethylene (UHMWPE)
