Abstract:
A method for reducing yellowness of a polyetherimide solution, including exposing a first solution including a solvent and a polyetherimide to light under conditions effective to provide a second solution having a yellowness index that is 1 to 100 units less than the yellowness index of the first solution, as determined according to ASTM D1925. Another aspect is a method for reducing yellowness of a polyetherimide solution including acidifying a first solution including a solvent and a polyetherimide to provide a second solution having a pH less than 5 under conditions effective for the second solution to attain a yellowness index that is 1 to 30 units less than the yellowness index of the first solution, as determined according to ASTM D1925. Polyetherimides prepared according to the method, and compositions and articles including the polyetherimide are also described.

Claim (Index 3):
