  1. In the absence of an indication to the contrary, an invention is classified in the last appropriate place within each main group. [2]
  2. In this sub-class, group C08G 18/00 takes precedence. A second classification should be given if the polymers are obtained by reactions forming specific linkages for which an appropriate group is provided. [2]
  3. In the absence of an indication to the contrary, in groups C08G 67/00-C08G 79/00 macromolecular compounds obtained by reactions forming two different linkages in the main chain are classified only according to the linkage present in excess. [2]
