Polyesters having been prepared in the presence of compounds having one reactive group or more than two reactive groups

Introduced: July 1974

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 > Dicarboxylic acids and dihydroxy compounds > Polyesters having been prepared in the presence of compounds having one reactive group or more than two reactive groups

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 > Dicarboxylic acids and dihydroxy compounds > Polyesters having been prepared in the presence of compounds having one reactive group or more than two reactive groups

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 1990.
