Olefin polymers are a class of synthetic polymers derived from olefin monomers, which are hydrocarbons containing at least one carbon-carbon double bond. The most common olefins used for polymerization are ethylene and propylene. These monomers undergo addition polymerization, where the double bond breaks and monomers link together to form long chains. The resulting polymers are characterized by their high molecular weight and their saturated hydrocarbon backbone.

Polyethylene, derived from ethylene, is the most widely produced plastic globally. It exists in various forms, including low-density polyethylene (LDPE) and high-density polyethylene (HDPE), which differ in their branching structures and consequently their physical properties. LDPE is flexible and transparent, used in films and bags, while HDPE is rigid and strong, found in bottles and pipes. Polypropylene, derived from propylene, is also a versatile polymer known for its strength, heat resistance, and chemical resistance. It is used in textiles, automotive parts, and packaging.

The properties of olefin polymers can be tailored through various methods, including controlling the molecular weight, molecular weight distribution, and the degree of branching. These polymers are valued for their low cost, ease of processing, excellent electrical insulation properties, and good chemical resistance, making them ubiquitous in packaging, construction, automotive, and consumer goods industries. Their recyclability also contributes to their widespread use.
