| 221 | DF | .~ Compound of indeterminate structure, prepared by reacting a heterocyclic compound of known structure; a heterocyclic ring is one having as ring members only carbon and at least one hetero atom selected from nitrogen and chalcogen (oxygen, sulfur, selenium, or tellurium) {9} |
| 232 |  | .~.~ The heterocyclic compound reactant contains a carboxylic acid anhydride ring {7} |
| 233 | DF | .~.~.~> An additional reactant is an alkadiene polymer {1} |
| 235 | DF | .~.~.~> An additional olefinic reactant is copolymerized with an unsaturated carboxylic acid anhydride so that the anhydride moiety forms part of the polymer backbone (i.e., addition polymerization) |
| 236 | DF | .~.~.~> An additional reactant is a sulfur compound |
| 237 | DF | .~.~.~> With organic phosphorus compound |
| 238 | DF | .~.~.~> An additional reactant is a polyoxyalkylene compound |
| 239 | DF | .~.~.~> An additional reactant is a hydroxylamine or an alcoholic or phenolic hydroxy compound {1} |
| 241 | DF | .~.~.~> An additional reactant is a copolymer having ethylene and acyclic olefin monomers (e.g., ethylene-alpha olefin copolymer or ethylene-butylene- -styrene terpolymer grafted with maleic anhydride, etc.) |
