C 08 G

MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING CARBON-TO-CARBON UNSATURATED BONDS [2]

Notes

(1)	In this subclass, group C 08 G 18/00 takes precedence over the other groups. A further classification is given if the polymers are obtained by reactions forming specific linkages for which an appropriate group is provided. [2]

(2)	Within each main group of this subclass, in the absence of an indication to the contrary, classification is made in the last appropriate place. [2]

(3)	In groups C 08 G 61/00 to C 08 G 79/00, in the absence of an indication to the contrary, macromolecular compounds obtained by reactions forming two different linkages in the main chain are classified only according to the linkage present in excess. [2]

Addition polymers of aldehydes or cyclic oligomers thereof or of ketones; Addition copolymers thereof with less than 50 molar percent of other substances [2]

Polymerisation initiated by wave energy or by particle radiation [2]

Polymerisation by using compounds which act upon the molecular weight, e.g. chain-transferring agents [2]
