Abstract: The invention relates to a composition comprising one or more polymers as component A and one or more diphenylphosphino compounds, in particular diphenylphosphino (meth)acrylate or (meth)acrylamide based compounds, as component B. Further, the present invention relates to the use of such diphenylphosphino compounds for stabilizing a polymer composition with respect to exposure to heat and/or mechanical stress during processing.

Abstract: The present invention relates to tetra-nuclear neutral copper (I) complexes that have a cubane-like structure, wherein said complexes further comprise diarylphosphine ligands which are bonded via phosphorus atoms. Furthermore, the present invention refers to methods for generating such copper (I) complex and to uses thereof. The present invention further relates to cubane-like conjugates that comprise moiety of the copper (I) complexes of the invention. Formula (A), each L is independently from each other an optionally substituted diary lphosphine residue of Formula (A1): PHSr2 (A1).
