Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
71 words
A composition comprising: a combination of an aqueous dispersion of an optionally substituted poly-3,4 alkylene dioxythiophene cation and an associated polyanion; and 1% (w/v) to 100% (w/v) of at least one or more organic solvents, wherein the one or more organic solvents have a boiling point between from about 81.6° c.to about 290° C., wherein at least 30% (w/v) of the water from the aqueous dispersion is removed from said combination.
Claim 2
Dependent Claim
71 words
A composition comprising: a combination of an aqueous dispersion of an optionally substituted poly-3,4 alkylene dioxythiophene cation and an associated polyanion; and 1% (w/v) to 100% (w/v) of at least one or more organic solvents, wherein the one or more organic solvents have a boiling point between from about 81.6° c.to about 290° C., wherein at least 30% (w/v) of the water from the aqueous dispersion is removed from said combination.
Claim 3
Dependent Claim
