Aqueous dispersions of conjugated polymers, e.g. polyacetylene, used for the production of coatings by ink-jet printing, e.g. antistatic coatings, strip conductors, opto-electronic components and solar cells

摘要

u Aqueous dispersions of conjugated polyacetylenes. Aqueous dispersions of conjugated polymers of formula (1), in which R 1>-R 6>H, 1-20C alkyl (acyclic or cyclic), 1-20C alkenyl or optionally substituted 1-20C aryl (optionally containing hetero-atoms such as O, N or S); x, y, z : 0-1000 (at least one of these is 1 or more) . Independent claims are included for (1) aqueous dispersions of poly-(phenylacetylenes) (2) aqueous dispersions of polyacetylene (3) a method for the production of these dispersions in an aqueous reaction mixture with the aid of a palladium catalyst (4) polymerisation of alkynes by this method (5) ink jet printing of these dispersions (6) coatings obtained by using these dispersions .
