Note

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