ABS# Fiber-graded poly(propylene) was modified by polyester-amide-based
     dendritic nanostructures with the aim of improving its dyeability. Two
     different dendritic polymers were used and the dendritic nanostructures
     were formed in situ via reactive blending with maleic anhydride-modified
     poly(propylene). Samples were chosen exploiting a 4-component mixture
     design. Thermal, morphological, and rheological characterizations showed
     domains with different size and distribution were formed and primary
     properties of the dendritics determined the characteristics of the
     resulted domains. Morphological parameters were quantified by digital
     analysis of scanning electron microscope images. Thermal and rheological
     behavior also demonstrated good agreements with the inferred morphology
     of the formed dendritic domains. The modified samples were then dyed with
     dispersed dyestuffs. A variety of substantivities were obtained, and
     some of the modified samples showed a significant enhancement in dyeing
     properties. A predictive model was developed for K/S ratio, where K and
     S are absorption and scattering coefficients of the Kubelka-Munk
     one constant theory, respectively.
