Abstract
Abstract The dye receptivity of polyolefins is improved by mixing 100 parts by weight of at least one polymer or copolymer of a 1olefin having two through eight carbon atoms per molecule with one to 20 parts by weight of a novel dye-receptive nonbasic polyamide modifier produced by polycondensing a diamine of which both amino groups are secondary with a hydrocarbon dicarboxylic acid.
