The C=C unsaturation in all these structures is 1,2-disubstituted, so initiation and propagation by free-radical and cationic mechanisms are sluggish. Hence, they elicit slow processes and poor yields of macromolecular structures though, ultimately, crosslinked materials are generated (as in the case of classical oxido-polymerisation discussed in Chapter 2). Preparation of blown oils by thermal treatment >300 C is also a poor approach because of substantial losses associated with thermal degradation. It follows that applications are not particularly attractive in practical terms except in the traditional realm of siccative paints and inks.
