Beschreibung
Zusammenfassung:	The invention provides a polyurethane elastomeric composition comprising a hard segment and a soft segment, wherein the soft segment is formed from: (a) at least one polycarbonate macrodiol, or a combination of at least one polyether macrodiol and at least one polycarbonate macrodiol; and (b) at least one polysiloxane macrodiol wherein the polysiloxane macrodiol is of formula (I): (wherein R1, R2, R3, R4, R5 and R6 are each independently an optionally substituted straight chain, branched or cyclic, saturated or unsaturated hydrocarbon radical and n is an integer from 1 to 100).
