Abstract
Electrically conductive polythiopheneamine polymer networks are provided comprising conjugated crosslinks between polythiopheneamine polymer segments of the network. The network can be formed by crosslinking amine functional polythiopheneamine polymers, such as by crosslinking condensation reaction with conjugated polyketone crosslinkers. The amine functional polythiopheneamine polymers can be prepared by polymerization, such as by electropolymerization of amine functional thiophene monomers (the amine functionality generally being protected during polymerization) and, optionally, suitable conjugated copolymerization monomers such as thiophene, pyrrole and/or amine functional pyrrole.

14. A process for producing an electrically conductive polythiopheneamine polymer network comprising conjugated crosslinking between polythiopheneamine polymer segments, comprising:
-
A) producing polythiopheneamine polymers by; 1) protecting the amine functionality of amine functional thiophene monomers selected from 2-thiopheneamine, 3-thiopheneamine and any mixture thereof by protecting reaction with acetone in the presence of pTSA; and 2) forming polythiopheneamine polymers having an average polymer chain length of 20 to 30 monomer units by electropolymerization of reactant monomers consisting essentially of (a) 5 to 50 mole percent of said amine functional thiophene monomers and (b) 50 to 95 mole percent conjugated copolymerization monomers selected from the group consisting of thiophene and pyrrole and any mixture thereof; and 3) acid hydrolysis of the polythiopheneamine to form polythiopheneamine polymers having free amine functionality B) then adding an electrical conductivity enhancing dopant; and C) in any order with step (B), crosslinking the amine functional polythiopheneamine polymers to form said network having conjugated crosslinks between polythiopheneamine polymer segments of the network.
