- 4. The composition according to claim 1, wherein the anaerobic curative is a trithiadiaza pentalene material represented by a member selected from the group consisting of: wherein R7 is C1-4 alkyl; wherein Ph is and p-TlO or p-OTl is and wherein R and R2 are as described in claim 1, and a is an integer between 1-3.
- 5. The composition according to claim 1, wherein the anaerobic curative is wherein R and R2 are as described in claim 1, and a is an integer between 1-3.
- 6. A composition comprising anaerobically cured products of the composition according to claim 1.
- 7. A method of using as a curative for anaerobic adhesives compounds within the following structure: wherein A and A1 are selected from O and N; R, R1, R2 and R3 are the same or different, and selected from hydrogen, alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, having from 1 to about 30 carbon atoms, and optionally substituted or interrupted with a heteroatom, and heterocyclic structures, or R1 and R3, taken together, join to form a cyclic structure having from about 20 to about 28 ring atoms, and together represent dialkyl substituted polyether structures that may be substituted or interrupted with the trithiadiaza pentalene structure, which itself is optionally substituted by A1, R2, or R3, as defined above, a step of which comprises providing the curative for use with the anaerobic adhesive.
- 8. A method of preparing an anaerobic adhesive composition, comprising the steps of:mixing together a (meth)acrylate component and an anaerobic curative within the following structure: wherein A and A1 are selected from O and N; and R, R1, R2 and R3 are selected from alkyl, alkenyl, cycloalkyl, cycloclkenyl, aryl, having from 1 to about 30 carbon atoms, and are optionally substituted or interrupted with a heteroatom, and heterocyclic structures, or R1 and R3 taken together join to form a cyclic structure having from about 20 to about 28 ring atoms, and together represent dialkyl substituted polyether structures that are optionally substituted or interrupted with the trithiadiaza pentalene structure, which itself is optionally substituted by A1, R2, or R3, as defined above.
- 9. The composition according to claim 1, further comprising a peroxide compound.
- 10. The composition according to claim 1, further comprising saccharin.
- 11. A method of using an anaerobic curative within the following structure: wherein A and A1 are selected from O and N; and R, R1, R2 and R3 are selected from alkyl, alkenyl, cycloalkyl, cycloclkenyl, aryl, having from 1 to about 30 carbon atoms, and are optionally substituted or interrupted with a heteroatom, and heterocyclic structures, or R1 and R3 taken together join to form a cyclic structure having from about 20 to about 28 ring atoms, and together represent dialkyl substituted polyether structures optionally substituted or interrupted with the trithiadiaza pentalene structure, which itself is optionally substituted by A1, R2, or R3, as defined above as a replacement for acetyl phenylhydrazine in anaerobic adhesive compositions, a step of which comprises providing the curative for use in the anaerobic adhesive.
- 12. The composition according to claim 9, further comprising saccharin.
