Heat-stable polymers based on bis-imides and oligomeric amines

Abstract

Abstract IN WHICH THE OXYGEN ATOM IS BONDED TO A CARBON ATOM OF THE RADICAL R, THE NUMBER OF IMIDE GROUPS INTRODUCED BY THE BIS-IMIDE BEING FROM 1.1 TO 50 PER-NH2 GROUP INTRODUCED BY THE POLYAMINE. O=R IN WHICH X REPRESENTS A NUMBER RANGING APPROXIMATELY FROM 0.1 TO 2 AND R REPRESENTS A DIVALENT HYDROCARBON RADICAL HAVING 1 TO 8 CARBON ATOMS, DERIVED FROM AN ALDEHYDE OR FROM A KETONE OF GENERAL FORMULA: H2N-(PHENYLENE)-R-((H2N-)-PHENYLENE)-R)X-(PHENYLENE)-NH2 WHERE N REPRESENTS AN INTEGER FROM 1 TO 3 OR SEVERAL PHENYLENE OR CYCLOHEXYLENE RADICALS JOINTED TO ONE ANOTHER BY A SIMPLE VALENCY BOND OR BY AN OXYGEN OR SULPHUR ATOM OR BY AN INERT GROUP, AND (B) A POLYAMINE OF AVERAGE GENERAL FORMULA: -(CH2)N-(PHENYLENE)-(CH2)N- -(NAPHTHALYLENE)-, -(1H-1,3,4-TRIAZOL-3,5-YLENE)-, OR -(PYRIDYLENE)-, -(1,8-NAPHTYRIDYLENE)-, SELECTED FROM MALEIC, CITRACONIC, ITACONIC, PYROCINCHONIC AND DICHLOROMALEIC ANHYDRIDE AND DIELS-ALDER REACTION PRODUCTS THEREOF WITH AN ACYCLIC, ALICYCLIC OR HETEROCYCLIC DIENE AND A REPRESENTS A DIVALENT ORGANIC RADICAL POSSESSING 2 TO 30 CARBON ATOMS SELECTED FROM A LEANER OR BRANCHED ALKYLENE RADICAL HAVING LESS THAN 13 CARBON ATOMS, A PHENYLENE OR CYCLOHEXYLENE RADICAL OR A RADICAL OF FORMULA: D<(-CO-O-CO-) IN WHICH D REPRESENTS A DIVALENT ORGANIC RADICAL CON TAINING A CARBON-CARBON DOUBLE BOND DERIVED FROM AN ANHYDRIDE OF THE GENERAL FORMULA: DI((-CO-D-CO-)>N-)-A 1. A POLYMER WHICH CONSISTS ESSENTIALLY OF A THREEDIMENSIONAL POLYIMIDE OBTAINED BY REACTING, BETWEEN 50* C. AND 350*C., (A) A BIS-IMIDE OF GENERAL FORMULA:
