Viscosimetría de las fibras de poliéster

Joaquín Gacén Guillén, Diana Cayuela Marín, Milena Tzvetkova


The viscosimetric constants were determined for several polyester fibres that differ in molecular weight and composition (homopolymers, copolymers, branched polymers, etc.). Calculating intrinsic viscosity from a single polymer dissolution, using the constants given in the bibliography, seems to lead to very similar values to those obtained from extrapolating the data from solutions of several concentrations.
