Abstract
Processes for chemically treating mixed aromatic feedstock to form thermoset aromatic resins are provided. The thermoset materials possess high compressive strength and find particular use in load-bearing applications, for example, infrastructure applications, as proppants, and as components in composite materials.
Claims13
A method of making a thermoset material from a mixed aromatic feedstock comprising:
- contacting a linker agent and a catalyst with a mixed aromatic feedstock at a temperature effective to react the linker agent with molecules in the mixed aromatic feedstock,
- wherein the contacting is conducted at a first pressure for a first time;
- and curing reaction products formed during the first time at a second pressure for a second time,
- wherein the second pressure is higher than the first pressure;
- wherein the linker agent contains at least two different functional groups that can react with the molecules in the mixed aromatic feedstock;
- and
- wherein the thermoset material has a compressive strength greater than about 100 MPa, when measured according to ASTM D695.
