Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
177 words
A one-step process for making solid electrically conducting organic polymers comprising the steps of: combining an amount of a monomer selected from a group consisting of N-alkyl carbazole and N-alkyldihalocarbazole monomers or combination thereof of the general formula ##STR3## where R is H or CH 3 , X is H and both Y's are Br or I, or Y is H and both X's are Br or I, with an amount of I 2 wherein said I 2 functions as a charge transfer acceptor dopant and heating said combination to form a liquid melt solution thereof; wherein the concentration of said monomers in said melt solution is in the range of 1% to 60% by weight and wherein the concentration of said I 2 is from about 99% to 40% by weight; polymerizing and chemically doping the monomer in said melt solution at a temperature between 80° C. and 200° for a time sufficient to produce the degree of polymerization desired at the temperature selected using an atmosphere selected from inert gas, air, or a partial vacuum.
Claim 2
Dependent Claim
