DEFINITION

Classification: 508/499

With hydrocarbon polymer, organic halogen compound, or organic non-carboxylic acid ester chalcogen compound:

(under subclass 496) Compositions which contain, in addition to the specified carboxylic acid ester, an organic halogen compound, a polymeric hydrocarbon or an organic chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) 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 496, provided there is also present one of an organic halogen compound, a hydrocarbon polymer, or an organic chalcogen compound that is not a carboxylic acid ester.

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

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