Abstract

Described herein is a polymerized biorenewable, petroleum based, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.0 to about 5.0, and sulfur content ranging from 0.001 wt % to about 8 wt %. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

First claim

The invention claimed is:

1. A polymerized petroleum based oil comprising:
a petroleum based oil crosslinked with a sulfur-containing compound and having
(a) a polymeric distribution having about 2 to about 80 wt % oligomer content;
(b) a polydispersity index ranging from about 1.0 to about 5.0; and
(c) sulfur content ranging from 0.001 wt % to about 8 wt %.

2. The polymerized petroleum based oil of claim 1 , herein the polymeric distribution has about 15 to about 60 wt % oligomer content.

3. The polymerized petroleum based oil of claim 1 , wherein the polydispersity index ranges from about 1.30 to about 2.20.

4. The polymerized petroleum based oil of claim 1 , wherein the sulfur content is less than about 6 wt %.

5. The polymerized petroleum based oil of claim 1 , herein the sulfur content is less than about 4 wt %.

6. The polymerized petroleum based oil of claim 1 , herein the sulfur content is less than about 2 wt %.

7. The polymerized petroleum based oil of claim 1 , having a flash point ranging from about 100° C. to about 400° C.

8. The polymerized petroleum based oil of claim 1 , having a flash point ranging from about 200° C. to about 350° C.

9. The polymerized petroleum based oil of claim 1 , having a flash point ranging from about 245° C. to about 275° C.

10. The polymerized petroleum based oil of claim 1 , further comprising at least one from the group consisting of thermoplastic elastomeric and plastomeric polymers, polyphosphoric acid, anti-stripping additives, warm mix additives, and fibers.

11. The polymerized petroleum based oil of claim 1 , wherein the sulfur-containing compound is elemental sulfur.

12. The polymerized petroleum based oil of claim 11 , wherein the crosslinking comprises heating to about 130° C to about 250° C.

13. The polymerized petroleum based oil of claim 11 , wherein the crosslinking comprises heating to about 130° C. to about 220° C.

14. The polymerized petroleum based oil of claim 11 , wherein the crosslinking comprises heating to about 160° C. to about 200° C.

15. The polymerized petroleum based oil of claim 1 , wherein the polymerized petroleum based oil has a sulfur content of 0.01 wt % to 8 wt %.

16. A modified asphalt comprising the polymerized petroleum based oil of claim 1 .

17. A modified asphalt for use in compositions for paving roads comprising the polymerized petroleum based oil of claim 1 .

18. A modified asphalt for use in compositions for roofing materials comprising the polymerized petroleum based oil of claim 1 .

19. A rejuvenator for use in asphalt comprising the polymerized petroleum based oil of claim 1 .

20. A performance grade modifier for use in asphalt comprising the polymerized petroleum based oil of claim 1 .

21. A compatibilizer for use in asphalt comprising the polymerized petroleum based oil of claim 1 .

22. A modified asphalt, comprising:
(a) about 60 to about 99.9 wt % asphalt binder; and
(b) about 0.1 to about 40 wt % polymerized petroleum based oil comprising
a petroleum based oil crosslinked with a sulfur-containing compound and having
i. a polymeric distribution haying about 2 to about 80 wt % oligomer content;
ii. a polydispersity index ranging from about 1.0 to about 5.0; and
iii. sulfur content less than about 8 wt %.

23. The modified asphalt of claim 22 , further comprising at least one from the group consisting of thermoplastic elastomeric and plastomeric polymers, polyphosphoric acid, anti-stripping additives, warm mix additives, emulsifier, and fibers.

24. A modified asphalt, comprising:
(a) about 60 to about 99.9 wt % asphalt binder; and
(b) about 0.1 to about 40 wt % of a blend of polymerized petroleum based oil and unmodified biorenewable oil, petroleum based oil, previously modified or functionalized oil, wherein the polymerized petroleum based oil comprises
a petroleum based oil crosslinked with a sulfur-containing compound and having
i. a polymeric distribution having about 2 to about 80 wt % oligomer content,
ii. a polydispersity index ranging from about 1.0 to about 5.0; and
iii. sulfur content less than about 8 wt %.

25. The modified asphalt of claim 24 , further comprising at least one from the group consisting of thermoplastic elastomeric and plastomeric polymers, polyphosphoric acid, anti-stripping additives, warm mix additives, emulsifier, and fibers.
