stable , concentrated solutions of high molecular weight polyaniline . in order to process high quality fibers and other articles possessing good mechanical properties , it is known that solution concentrations of the chosen polymer should be in the range from 15 - 30 % . moreover , it is desirable to use the highest molecular weight consistent with the solubility properties of the polymer . however , such solutions are inherently unstable , forming gels before processing can be achieved . the present invention describes the addition gel inhibitors to the polymer solution , thereby permitting high concentrations ) of high molecular weight & gt ; 120 , 000 , and & gt ; 30 , 000 ) emeraldine base polyaniline to be dissolved . secondary amines have been used for this purpose in concentrations which are small compared to those which might otherwise be used in a cosolvent role therefor . the resulting solutions are useful for generating excellent fibers , films , coatings and other objects , since the solutions are stable for significant time periods , and the gis are present in too small concentrations to cause polymer deterioration . it is demonstrated that the gis found to be useful do not act as cosolvents , and that gelation times of the solutions are directly proportional to the concentration of gi . in particular , there is a preferred concentration of gi , which if exceeded causes structural and electrical conductivity degradation of resulting articles . heating of the solutions significantly improves solubility .
