DEFINITION

Classification: 508/465

Plural -C(=O)O- groups attached directly or indirectly to each other by nonionic bonding (e.g., estolides of hydroxy carboxylic acids, etc.):

(under subclass 463) Compositions wherein an additional -C(=O)O- group is attached directly or indirectly to the -C(=O)O- group by nonionic bonding.

(1) Note. The additional -C(=O)O- group does not have to be present as part of a carboxylic acid ester group.

(2) Note. An example of a component provided for herein is [figure]
