Full Title

Full titles differ between systems:

IPC:

Macromolecular compounds obtained by reactions forming in the main chain of the macromolecule a linkage containing nitrogen, with or without oxygen or carbon, not provided for in groups > Polycondensates having nitrogen-containing heterocyclic rings in the main chain of the macromolecule; Polyhydrazides; Polyamide acids or similar polyimide precursors > Polyimides; Polyester-imides; Polyamide-imides; Polyamide acids or similar polyimide precursors > Unsaturated polyimide precursors

CPC:

Macromolecular compounds obtained by reactions forming a linkage containing nitrogen with or without oxygen or carbon in the main chain of the macromolecule, not provided for in groups C08G12/00 - C08G71/00 > Polycondensates having nitrogen-containing heterocyclic rings in the main chain of the macromolecule > Polyimides; Polyester-imides; Polyamide-imides; Polyamide acids or similar polyimide precursors > Unsaturated polyimide precursors
