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.
Claims25
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 %.
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 %.
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 %.
