Abstract

Described herein is a polymerized biorenewable, petroleum based, previously modified, or functionalized oil, comprising a polymeric distribution ranging from about 2 to about 80 wt % oligomer content, a hydroxyl value ranging from about 0 to about 400, and an iodine value ranging from about 0 to about 200. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

Claims (12)

1. A modified asphalt comprising a compatibilizing composition, the compatibilizing composition comprising:

(a) a polyol ester;

(b) a hydroxyl value ranging from about 0 to about 400; and

(c) an iodine value ranging from about 0 to about 200;

wherein the polyol in the polyol ester is derived from sorbitol, polyglycerol, pentaerythritol, a copolymer comprising sorbitol, a copolymer comprising polyglycerol, a copolymer comprising sorbitol and polyglycerol, or a combination thereof.

2. The modified asphalt of claim 1 , wherein the polyol is synthetically or derivable from biorenewable sources.

3. The modified asphalt of claim 1 , wherein the polyol in the polyol ester is sorbitol, a copolymer comprising sorbitol, or a combination thereof.

4. The modified asphalt of claim 1 , wherein the ester in the polyol ester is selected from the group consisting of pentaerythritol esters, sorbitol esters, and combinations thereof.

5. The modified asphalt of claim 1 , wherein the polyol ester is a polyglycerol ester.

6. The modified asphalt of claim 1 , wherein the Hildebrand Solubility parameter of the polyol ester ranges from about 6 to about 12.

7. The modified asphalt of claim 1 for use in compositions for paving roads.

8. The modified asphalt of claim 1 for use in compositions for roofing materials.
