Resin compositions made of high-performance polymers blended with molecular glass as rheological modifiers are disclosed. The high-performance polymers include thermoplastics, such as polysulfones, polyimides, poly(ether imides), polyketones, poly(ether ketones), and combinations thereof. The molecular glasses are amorphous, non-oligomeric, and have one or more functional groups that promote miscibility of the molecular glass with the high-performance polymers to produce a resin composition with low melt viscosity. Incorporation of the molecular glasses into the high-performance polymers does not alter the Young's modulus and yield stress values of the high-performance polymers. |
