DEFINITION

Classification: 508/505

With hydrocarbon polymer or organic non-carboxylic acid ester oxygen compound (e.g., polybutene, dimer carboxylic acids, alcohols, etc.):

(under subclass 463) Compositions which contain, in addition to the specified carboxylic acid ester, a polymeric hydrocarbon or an organic oxygen compound that is not a carboxylic acid ester.

(1) Note. An additional carboxylic acid ester may be present that is not the specified carboxylic acid ester of subclass 463, provided that there is also present one of a polymeric hydrocarbon or an organic oxygen compound that is not a

carboxylic acid ester.

(2) Note. An organic oxygen compound is one wherein oxygen is attached directly or indirectly by nonionic bonding to carbon of an organic compound.

(3) Note. See Notes to the Class Definition for the definition of an organic compound.
