Beschreibung
Zusammenfassung:	Disclosed herein is a composition comprising: a cross linked polysiloxane/polyimide block copolymer having a siloxane content of 10 to 45 weight percent, based on the total weight of the block copolymer, wherein the cross linked polysiloxane/polyimide block copolymer has a heat distortion temperature measured at 0.44 megaPascals that is at least 5 degrees Celsius greater than the heat distortion temperature of the polysiloxane/polyimide block copolymer prior to cross linking, and wherein the cross linked polysiloxane/polyimide block copolymer has an E' modulus measured at 30 degrees Celsius that is greater than or equal to 115% of the E' modulus measured at 30 degrees Celsius of the polysiloxane/polyimide prior to cross linking. The composition is useful in making covered conductors.
