SummaryReaction of methyl linoleate with di‐tert.‐butyl peroxide yields tert.‐butyl alcohol and dehydro‐polymers of methyl linoleate as the main products. The dehydro‐dimers and higher dehydro‐polymers of methyl linoleate contain conjugated diene unsaturation, thus indicating the involvement of the pentadiene system −CH=CH−CH 2 −CH=CH− in the reaction. Methyl stearate yields dehydro‐polymers on reaction with di‐tert.‐butyl peroxide, thus indicating that reaction can occur at points in the fatty acid chains not activated by the proximity of olefinic double bonds.
