Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
69 words
A polyvalent metal salt of an oxidized and amidified non-benzenoid hydrocarbon wax obtained by the process consisting essentially of the steps of (b) oxidizing a non-benzenoid hydrocarbon wax (a), (c) thereafter amidifying the oxidized wax of step (b) with ammonia or an amine containing amino hydrogen and an additional isocyanate reactible active hydrogen, and finally (d) forming a polyvalent metal salt of the previously amidified product of step (c).
Claim 2
Dependent Claim
69 words
A polyvalent metal salt of an oxidized and amidified non-benzenoid hydrocarbon wax obtained by the process consisting essentially of the steps of (b) oxidizing a non-benzenoid hydrocarbon wax (a), (c) thereafter amidifying the oxidized wax of step (b) with ammonia or an amine containing amino hydrogen and an additional isocyanate reactible active hydrogen, and finally (d) forming a polyvalent metal salt of the previously amidified product of step (c).
Claim 3
Dependent Claim
26 words
The composition of claim 1 where the polyvalent metal is a member of the following group of the Periodic Table: IIA, IIB, IIIA, IVA and IVB.
Claim 4
Dependent Claim
17 words
The composition of claim 2 where the wax is a petroleum or synthetic wax or mixtures thereof.
Claim 5
Dependent Claim
57 words
The composition of claim 3 where a. the wax has a melting point of about 120°-230° F. prior to oxidation; b. the wax has an acid number of about 10 to 60 and/or a saponification number of about 20 to 150 after oxidation; c. the wax contains about 0.05 to 1.0 percent nigrogen by weight after amidification.
Claim 6
Dependent Claim
21 words

The composition of claim 6 where the polyvalent metal is calcium.
Claim 10
Dependent Claim
26 words
The composition of claim 8 where the wax is a microcrystalline wax, an alpha olefin wax, a Fischer-Tropsch wax, a polyethylene type wax, or mixtures thereof.
