ABSTRACT:
By the incorporation of small amounts of specific polyamides into polyalkenes, such as polypropylene and polyethylene, it is possible to significantly improve the dyeing properties, including color intensity, color homogeneity and color fastness, of the polyalkene. Polyamides useful for this purpose are derived from mixed dicarboxylic acids, diamine and triamine containing two primary and one tertiary amine groups.
