  • Patent number: 8586702
    Abstract: Substituted 3,4-propylenedioxythiophene monomers may be prepared by reacting 3-allyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine or 3,3-diallyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine with a thiol having a hydrocarbyl moiety optionally containing one or more heteroatom-containing functional groups under radical addition conditions under radical addition conditions. Such monomers may be used in homo- or copolymerization processes to obtain thiophene-type polymers containing substituents (which may bear functional groups such as silane, thiol, hydroxyl, carboxylic acid, amine, sugar groups, polyoxyalkylene, and the like). Crosslinkers useful for introducing crosslinking into thiophene-type polymers may be prepared by reacting 3-allyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine with a compound having two or more thiol groups under radical addition conditions.
