Abstract

Procedure for obtaining polyurethane-polyureas bearing uretdione groups, by reaction of a) polyisocyanates containing uretdione groups with aliphatically linked isocyanate and uretdione groups, with polyisocyanates that may be mixtures with polyisocyanates free of uretdione groups and containing isocyanate groups linked aliphatically with b) chain prolonging agents containing at least two active hydrogen atoms, characterized in that primary and/or secondary diamines with aliphatically linked amino groups or hydrazines with at least two hydrogen atoms linked with the hydrogen.
