polyolefin

https://doi.org/10.1351/goldbook.15255
Polymer prepared from an olefin.
Notes:
  1. A typical polyolefin macromolecule is derived from an alkene and is described by the monomeric unit: \(\ce{-CR^1R^2\bond{-}CH2\bond{-}}\), where \(\ce{R^1}\) and \(\ce{R^2}\) are hydrogen, alkyl, or cycloalkyl. Polyolefins with 1,2-disubstituted monomeric units \(\ce{-CHR^1\bond{-}CHR^2\bond{-}}\) are rather rare, owing to low thermodynamic stability of their main chains caused by steric effects of the substituents.
  2. The structure-based name of a polyolefin prepared from an alkene is a polyalkylene.
