Introduced: July 1974

Title

Titles differ between systems:

IPC: Polyesters chemically modified by esterification

CPC: Polyesters chemically modified by esterification (C08G63/20 takes precedence; by after-treatment C08G63/91)

Full Title

Full titles differ between systems:

IPC:

Macromolecular compounds obtained by reactions forming a carboxylic ester link in the main chain of the macromolecule > Polyesters derived from hydroxy carboxylic acids or from polycarboxylic acids and polyhydroxy compounds > derived from polycarboxylic acids and polyhydroxy compounds > Polyesters chemically modified by esterification

CPC:

Macromolecular compounds obtained by reactions forming a carboxylic ester link in the main chain of the macromolecule (polyester-amides C08G69/44; polyester-imides C08G73/16) > Polyesters derived from hydroxycarboxylic acids or from polycarboxylic acids and polyhydroxy compounds > derived from polycarboxylic acids and polyhydroxy compounds > Polyesters chemically modified by esterification (C08G63/20 takes precedence; by after-treatment C08G63/91)

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 1974.
