olefinbased
Olefinbased (often written olefin-based) refers to materials and compounds derived primarily from olefins, the hydrocarbons containing at least one carbon–carbon double bond (alkenes). The term covers polymers and low-molecular-weight products produced by addition polymerization and related processes from olefin monomers such as ethylene, propylene, butenes, and higher olefins. Olefinbased materials are ubiquitous in modern plastics and elastomers, with properties largely governed by the identity of the olefin and the polymer architecture.
Common olefinbased polymers include polyethylene (PE) and polypropylene (PP), including their copolymers such as linear low-density
Production of olefinbased polymers typically involves addition polymerization of olefin monomers using catalysts that control tacticity,
Environmental and sustainability considerations center on end-of-life handling, recycling, and the use of feedstocks. Polyolefins are
