Any open-chain hydrocarbon having one or more double bonds.

(n) any unsaturated aliphatic hydrocarbon

Olefin is the old name for alkenes and is still used in the refining industry. Alkenes are hydrocarbons containing at least one carbon-carbon covalent double bond. The simplest alkene is ethylene (CH2 [..]

A hydrocarbon containing a carbon-carbon double bond.  Olefins are also known as alkenes.

A lightweight, synthetic fabric with a wool-like feel. Olefin is created when polymers are melted into a liquid and then run through a machine called a spinneret, which forces the long fiber through small holes. Fibers are then woven into fabric. Olefin is quick-drying, colorfast and resistant to deterioration. Relatively easy to care for, olefin i [..]

A synthetic fiber which is strong, lightweight, and abrasion resistant.  It also has a wicking property.  Olefin is used for upholstery fabric, carpets, and activewear fabric.

A class of unsaturated hydrocarbons

hydrocarbons characterized by having at least one double bond; specifically, any of a series of open-chain hydrocarbons such as ethylene.

(organic chemistry) Any of a class of unsaturated open-chain hydrocarbons such as ethylene; an alkene with only one carbon-carbon double bond.
