Abstract
Described herein is a polymerized biorenewable, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.30 to about 2.20, 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 method of polymerizing a biorenewable, previously modified, or functionalized oil, comprising:
- heating a biorenewable, previously modified, or functionalized oil to at least 100° C., wherein the oil comprises soybean oil, canola oil, rapeseed oil, castor oil, tall oil, sunflower oil, palm oil, peanut oil, safflower oil, corn oil, corn stillage oil, lecithin, an animal-based oil, or a combination thereof;
- adding a sulfur-containing compound to the heated oil;
- and
- allowing the sulfur-containing compound to react with the oil to produce a polymerized oil crosslinked with the sulfur-containing compound, the oil comprising
- a polymeric distribution having about 2 to about 80 wt % oligomer content, and
- a. sulfur content ranging from 0.001 wt % to 8 wt %.
A method of polymerizing a biorenewable, previously modified, or functionalized oil, comprising:
- heating a biorenewable, previously modified, or functionalized oil to at least 100° C.;
- adding a sulfur-containing compound to the heated oil;
- and
- allowing the sulfur-containing compound to react with the oil to produce a polymerized oil crosslinked with the sulfur-containing compound, the oil comprising
- a polymeric distribution having about 2 to about 80 wt % oligomer content, and
- a sulfur content ranging from 0.001 wt % to 8 wt %;
- wherein
- a weight ratio of the polymerized oil to a combination of the biorenewable, previously modified, or functionalized oil and the sulfur content of the polymerized oil is 1:1, or
- all sulfur-containing crosslinks present in the polymerized oil are between molecules of the biorenewable, previously modified, or functionalized oil, or
- a combination thereof.
A method of polymerizing a biorenewable, previously modified, or functionalized oil, comprising:
- heating a biorenewable, previously modified, or functionalized oil to at least 100° C.;
- adding a sulfur-containing compound to the heated oil;
- allowing the sulfur-containing compound to react with the oil to produce a polymerized oil crosslinked with the sulfur-containing compound, the oil comprising
- a polymeric distribution having about 2 to about 80 wt % oligomer content, and
- a sulfur content ranging from 0.001 wt % to 8 wt %;
- and
- further comprising passing a gas-containing stream through the reaction mixture during the reaction of the sulfur-containing compound with the oil, wherein the gas-containing stream is selected from the group consisting of nitrogen and inert gas.
