Abstract
Described herein is a polymerized biorenewable, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to 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.
Claims23
A polymerized oil comprising:
- a biorenewable, previously modified, or functionalized oil crosslinked with a sulfur-containing compound and comprising
- a polymeric distribution comprising about 2 to about 80 wt % oligomer content, and sulfur content ranging from 0.001 wt % to 8 wt %;
- wherein the biorenewable, previously modified, or functionalized 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.
A method of incorporating a polymerized oil in asphalt applications, comprising:
- adding a polymerized oil to treat reclaimed asphalt pavement millings (RAP) to be reused in asphalt pavements, thereby obtaining a modified asphalt, the polymerized oil comprising
- a biorenewable, previously modified, or functionalized oil crosslinked with a sulfur-containing compound and comprising
- a polymeric distribution comprising about 2 to about 80 wt % oligomer content, and
- sulfur content ranging from 0.001 wt % to 8 wt %;
- wherein the amount of the polymerized oil ranges from 0.1 to 40 wt % of the modified and rejuvenated asphalt, and wherein the biorenewable, previously modified, or functionalized 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.
A polymerized oil comprising:
- a biorenewable, previously modified, or functionalized oil crosslinked with a sulfur-containing compound and comprising
- a polymeric distribution comprising about 2 to about 80 wt % oligomer content, and sulfur content ranging from 0.001 wt % to 8 wt %;
- wherein
- all sulfur-containing crosslinks present in the polymerized oil are between molecules of the biorenewable, previously modified, or functionalized oil, or
- a combination thereof.
