Short disctoption of the project:

The practical goal of the project is the effective marketing of the developed invention concerning photogenerators of strong protic acids (PAG-s) based on innovative accelerating molecules. There are reasons for taking actions towards implementation of the results obtained in the SONATA base project (NCN) in the economic practice because:

1. New chemical compounds were developed for the role of PAGs,
2. These compounds shifted the light sensitivity of commercially available PAGs to the near-UV (UV-A) range and some of the derivatives to the visible spectrum,
3. The developed compounds in the process of synergistic interaction with iodonium salts lead to conversions of about 70% for epoxy monomers during cationic photopolymerization while for acrylic monomers (radical photopolymerization) (the conversion of monomers about >95% are obtained),
4. It is possible to obtain an increase in the speed of the whole process, a reduction of the polymerization time, and thus a possibility to lower the concentration of the initiator system used, and thus directly an increase in savings resulting from lower financial outlays for both,
5. The systems developed will be able to be used in much lower concentrations without slowing down the production rate of polymeric coatings or increasing the production rate.
