Two-layer shoe sole having an outsole of polyurethane-polyurea elastomers, and a process for the production thereof |
摘要 |
The invention relates to a two-layer shoe sole comprising i) an outsole of high-density polyurethane-polyurea elastomers and ii) a throughsole or comfort sole of low density produced by the one-shot process with the aid of the high-pressure method (RIM) by reacting a) organic polyisocyanates, b) relatively high-molecular-weight polyols, c) chain extenders and/or crosslinking agents, in the presence of d) catalysts, e) blowing agents and optionally f) auxiliaries and/or additives, where the formative component (c) for the production of the outsole (i) comprises primary aromatic polyamines, preferably alkyl-substituted phenylenediamines, containing at least one bonded alkyl radical in the ortho-position to each amino group, at least one of the alkyl radicals comprising more than 3 carbon atoms.
