Polyimide foams |
| abstract |
DISCLOSED HEREIN ARE POLYIMIDE FOAMS PREPARED FROM A MIXTURE OF (1) AN A-STAGED POLYIMIDE RESIN FORMING COMPOSITION HAVING A VOLATILE CONTENT OF AT LEAST 9% BY WEIGHT, AND (2) A B-STAGED POLYIMIDE RESIN HAVING A VOLATILE CONTENT OF LESS THAN 9% BY WEIGHT. THE MIXTURE IS HEATED TO AT LEAST THAT TEMPERATURE WHERE FOAMING OCCURS CONTEMPORANEOUSLY WITH THE POLYMERIZATION OF THE A-STAGED SYSTEM, TO FORM A POLYIMIDE FOAM HAVING A DENSITY UP TO 70 LBS./CU. FT. |
