composição polimérica, e, processo para produzir a mesma

摘要

Polymer compositions (I) comprising (a) polyolefin(s) and (b) block copolymer(s), in which component (b) comprises at least one hydrophobic block (A) made up essentially of isobutene units and at least one hydrophilic block (B) with an average mol wt. (Mn) of at least 1000, made up essentially of oxyalkylene units. Independent claims are included for (1) a method (M1) for coloring (I) with an aqueous dye formulation in which (I) is heated to above its glass transition point (Tg) but below its melting point (Tm) during and/or after treatment (2) a method (M2) for printing substrates made from pigmented or unpigmented (I) with a printing paste containing dye(s), in which (I) is heated as above during and/or after printing.
