Process for the preparation of polyimide foam |
| abstract |
A polyimide foam is prepared by heating a mixture comprising an alkyl ester of 4,4'-oxydiphthalic acid and a diamine at a temperature of 60° to 350° C. This foam is elastic and flame-retardant and has an excellent resistance to acid and alkali. |
