Abstract
The invention concerns the production of poly(arylene-vinylenes) and related polymers whose polymerization is triggered photochemically. For that purpose, the low molecular starting materials are firstly cooled to temperatures which are so low that in fact their activation into mostly chinoid intermediate stages (the “active” monomer) occurs; the thermally induced polymerization, however, either does not occur or barely takes place at all. The polymerization is instead triggered in a separate step by means of electromagnetic radiation of a suitable wavelength—either using the absorption behavior of the low-molecular starting compounds/the monomers, or mediated by means of photoinitiators and/or sensitizers.
