DEFINITION

Classification: 526/292.3

Contains oxygen other than as part of a carboxylic acid ester group:

(under subclass 292.1) Subject matter wherein said halogen-containing monomer also contains an oxygen atom other than as part of a carboxylic acid ester group.

(1) Note. This subclass excludes halogenated carbonate monomers, per se; however, a halogen-containing monomer which contains a carboxylic acid ester moiety and a carbonate moiety would be included herein; as would a halogen-containing monomer which contains a carboxylic acid ester moiety and a free carboxylic acid moiety.

291, 293 through 295, for a halogen-containing monomer which also contains a carbonate group.
