  • Polyurethane, method for production and use thereof
    Patent number: 6930161
    Abstract: A self-crosslinking, branched polyurethane preparable by reacting (A) at least one hydroxyl-terminated polyester with a number-average molecular weight of from 500 to 4000 daltons, containing based on the polyester (A) (a1) from 60 to 95% by weight of structural units derived from aliphatic starting products and (a2) from 5 to 40% by weight of structural units derived from aromatic starting products with (B) at least one partially blocked polyisocyanate containing on average per molecule more than 1.5 and less than 3 free isocyanate groups, the equivalents ratio of free isocyanate groups in the polyisocyanate (B) to hydroxyl groups in the polyester (A) being >1, to give an isocyanato-terminated polyurethane prepolymer which is chain-extended and/or blocked with (C) at least one compound containing on average per molecule at least two isocyanate-reactive functional groups; process for its preparation, and its use as a binder in coating materials, adhesives, and sealing compounds.
