摘要:
A polyimide composition includes 1 to 99 weight percent, preferably 70 to 99 weight percent, more preferably 75 to 95 weight percent of a first polyimide; and 1 to 99 weight percent, preferably 1 to 30 weight percent, more preferably 2 to 25 weight percent of a second polyimide, wherein the first polyimide and the second polyimide are different, and wherein the polyimide composition has a melt flow rate that is greater than a melt flow rate of the first polyimide and less than a melt flow rate of the second polyimide; an apparent viscosity that is less than an apparent viscosity of the first polyimide and less than an apparent viscosity of the second polyimide; and a notched Izod impact strength that is greater than a notched Izod impact strength of the first polyimide and greater than a notched Izod impact strength of the second polyimide.
