Abstract
Disclosed herein are compositions comprising an ionic crosslinking agent (e.g., compositions comprising crosslinked products prepared by ionically crosslinking a polymer derived from styrene and optionally butadiene using an ionic crosslinking agent). The present disclosure also relates to methods of making the disclosed compositions. The compositions disclosed herein can be used in a variety of applications including, but not limited to, asphalt compositions, paints, coatings, carpet compositions, paper binding and coating compositions, foams, or adhesives.
Claims16
An asphalt composition comprising:
- asphalt;
- aggregate;
- and
- a crosslinked product prepared by ionically crosslinking a random copolymer derived from styrene and butadiene using an ionic crosslinking agent.
An asphalt composition, comprising:
- asphalt;
- and
- a crosslinked product prepared by ionically crosslinking a random copolymer derived from styrene and butadiene using an ionic crosslinking agent, wherein the random polymer is further derived from glycidyl methacrylate, N-methylolacrylamide, or a combination thereof.
An asphalt composition, comprising:
- asphalt;
- and
- a crosslinked product prepared by ionically crosslinking a random copolymer derived from styrene and butadiene using an ionic crosslinking agent, wherein the ionic crosslinking agent includes zirconium.
A method of producing an asphalt composition, comprising:
- blending a random copolymer derived from styrene and butadiene, an ionic crosslinking agent, and asphalt at a blending temperature of 5° C. to 200° C.;
- and
- ionically crosslinking the random copolymer with the ionic crosslinking agent to form a crosslinked composition;
- and
- adding aggregate to the crosslinked composition.
