DEFINITION

Classification: 526/304

(under subclass 303.1) Subject matter wherein the amide monomer contains at least one carbon atom bonded to at least

one oxygen atom and wherein said carbon to oxygen bond is not part of an amide group.

(1) Note. Patents included within this subclass include those wherein two or more carbonyl groups are bonded to a nitrogen atom so as to form an imide group, e.g., [figure] [caption]etc.
