DEFINITION

Classification: 508/368

Heavy metal or aluminum in an organic phosphorus compound having four chalcogens bonded directly to the phosphorus:

(under subclass 110) Compositions which contain an organic phosphorus compound which (1) contains heavy metal or aluminum and (2) has four chalcogens (i.e., oxygen, sulfur, selenium, or tellurium) bonded directly to the phosphorus.

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

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

(3) Note. An example of a component provided for herein is (CH3O)2[end subscrpt]-P(S)S-Ti(OCH3[end subscrpt])3
