Polyurethane (PU) from methyl oleate (derived from sunflower oil) and ricinoleic acid (derived from castor oil) was synthesized using the AB-type self-polycondensation approach for the first time. In the present work, three novel AB-type monomers, namely, a mixture of 10-hydroxy-9-methoxyoctadecanoyl azide/9-hydroxy-10-methoxyoctadecanoyl azide (HMODAz), 12-hydroxy-9-cis-octadecenoyl azide (HODEAz)

The present invention relates to a compound with the following formula (I) where: R
1
is particularly a straight or branched alkyl group, a is a single or double bond; R
2
is particularly a hydrogen atom; R
3
and R
5
are a hydrogen atom when a is a single bond, and absent when a is a double bond; R
4
is a hydrogen atom or an OR
b
group, where R
b
is a hydrogen atom or an alkyl group including 1 to 12 atoms of carbon, and A
1
is a divalent alkylene radical.
