Beschreibung
Zusammenfassung:	Polyisocyanate-based polymers are formed by curing a reaction mixture containing at least one polyisocyanate and at least one isocyanate-reactive compound having at least two isocyanate-reactive groups in the presence of a copper catalyst that contains at least one copper atom associated with a polydentate ligand that contains at least one nitrogen-containing complexing site. La présente invention concerne des polymères à base de polyisocyanate qui sont formés par durcissement d'un mélange de réaction contenant au moins un polyisocyanate et au moins un composé réactif isocyanate ayant au moins deux groupes réactifs isocyanate en présence d'un catalyseur au cuivre qui contient au moins un atome de cuivre associé à un ligand polyvalent qui contient au moins un site de complexation contenant de l'azote.
