Single-Point Intrinsic Viscosity: Intrinsic Viscosity in the SEC-Viscometry

Eiichi Takatori, Takatoshi Shimura

Open full text 0 citations

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.
