Abstract

Methods of making miscible and compatible immiscible polymer blends are disclosed. The polymer blends have a polyimide as a component. The miscible polymer blends have a single glass transition temperature. The compatible polymer blends have two glass transition temperatures. The polymer blends may optionally include one or more fillers.
