Method for producing semi-rigid compact or cellular shaped bodies with a PUR base and the stabilization thereof; shaped bodies produced according to said method and the use thereof

摘要

This invention relates to a process for producing polyester-polyurethane compositions, and to the stabilization thereof in relation to hydrolytic ageing phenomena by an active ingredient combination comprising compounds containing carbodiimides with lactone derivatives, to mouldings produced therefrom and to the use thereof for semi-rigid, solid and/or cellular mouldings.
