Abstract
Many workers proposed an equation for a single point determination of intrinsic viscosity [η]. In these methods Solomon-Cuita's and Solomon Gotesman's equations were suitable with concentration of polymer c up to specific viscosity ηsp < 0.6, and Fikentscher's with concentration c nearly equal to ηsp = 1.5. In SEC-Viscometry, ηsp/c was equal to Solomon-Cuita's and Solomon Gotesman's. Significant data were ηsp and c.
