摘要：
Glutarimide polymers having an acid and anhydride content lower than the acid and/or anhydride content normally present in the glutarimide polymers. Blends of the reduced acid and anhydride glutarimide polymers with thermoplastic materials are disclosed. A process for altering the properties of imide polymers by reducing or substantially removing acid and anhydride levels normally present in the imide polymer is also disclosed.
