C08G63/00

Macromolecular compounds obtained by reactions forming a carboxylic ester link in the main chain of the macromolecule (polyester-amides C08G 69/44; polyester-imides C08G 73/16) [2, 5]

Note(s) Compounds characterised by the chemical constitution of the polyesters are classified in the groups for the type of polyester compound. Compounds characterised by the preparation process of the polyesters are classified in groups C08G 63/78-C08G 63/87 for the process employed. Compounds characterised both by the chemical constitution and by the preparation process are classified according to each of these aspects.[5]
