New compounds and unsaturated branched to manufacture polymers crosslinkable

The present invention relates to novel compounds and unsaturated branched difunctional, obtained from fatty acids. It also relates to a process for their preparation and their uses, particularly as monomers in the synthesis of polymers. In particular, the invention relates to compounds with amine functionality, acid, ester, nitrile, azide and alcohol, in particular from renewable resources, particularly useful in polymer synthesis. The invention also relates to polymers obtained from these novel compounds, including polyamides, and their use for the production of industrial objects or everyday life.
