MEHTOD FOR REACTING THERMOPLASTIC POLYURETHANES (I) WITH COMPOUNDS CONTAINING ISOCYANATE GROUPS

摘要

The invention relates to a method for reacting thermoplastic polyurethanes (i) with compounds containing isocyanate groups (ii), wherein compounds (iia) containing at least three aliphatic isocyanate-based groups and compounds (iib) containing two aromatic isocyanate-based groups are used in the form of the compounds (ii) containing isocyanate groups.
