Polysulphone compositions |
| abstract |
A FILM-FORMING COMPOSITION HAVING GOOD HEAT STABILITY WHICH COMPRISES (A) A POLYSULPHONE AND (B) AN IMIDE PERPOLYMER OBTAINED BY REACTING AN N,N''-BIS-IMIDE OF AN UNSATURATED DICARBOXYLIC ACID OF GENERAL FORMULA: (D<(-CO-N(-)-CO-))2-A IN WHICH D REPRESENTS A DIVALENT ORGAINIC RADICAL CONTAINING A CARBON-CARBON DOUBLE BOND AND A REPRESENTS A DIVALENT ORGANIC RADICAL POSSESSING AT LEAST TWO CARBON ATOMS, WITH A DI-PRIMARY DIAMINE OF GENERAL FORMULA H2N-B-NH2 IN WHICH B REPRESENTS A DIVALENT ORGANIC RADICAL POSSESSING NOT MORE THAN 30 CARBON ATOMS, THE QUANTITIES OF BISIMIDE AND OF DIAMINE BEING SUCH THAT THE RATIO NUMBER OF MOLD OF N,N''-BIS-IMIDE NUMBER OF MOLS OF DIAMINE IS BETWEEN 1.1 AND 50. |
