Polymer composition, useful in the form of e.g. fibers, yarns, fabrics and fleeces, comprises polyolefin and a block copolymer containing a hydrophobic block formed from isobutane unit and a hydrophilic block formed from oxalkylene unit

摘要

Polymer composition comprises at least a polyolefin and at least a block copolymer containing at least a hydrophobic block formed from isobutene units and a hydrophilic block formed from oxalkylene units, and the average molecular mass of the block copolymer is at least 1000 g/mol. An independent claim is included for a method of dyeing polymers comprising: treating the uncolored polymer composition with a formulation, water and a coloring material; and heating the polymer composition greater than its glass transition temperature and lower than its melting temperature during and/or after the treatment.
