RIGID FOAMS

A rigid foam including the reaction product of an (poly)isocyanate, and a polyethercarbonate polyol copolymer is described. The polyethercarbonate polyol copolymer is derived from the copolymerisation of one or more epoxides with CO2, wherein the total-CO2- content of the polyethercarbonate polyol c...

Zusammenfassung:	A rigid foam including the reaction product of an (poly)isocyanate, and a polyethercarbonate polyol copolymer is described. The polyethercarbonate polyol copolymer is derived from the copolymerisation of one or more epoxides with CO2, wherein the total-CO2- content of the polyethercarbonate polyol copolymer is between 1 and 40 wt %, the carbonate linkages are
