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.

First claim

1 . A composition comprising:
a crosslinked product prepared by ionically crosslinking a polymer derived from styrene and optionally butadiene using an ionic crosslinking agent.

2 . The composition according to claim 1 , wherein the polymer is polystyrene.

3 . The composition according to claim 1 , wherein the polymer is derived from styrene and butadiene.

4 . The composition according to claim 3 , wherein the polymer is a carboxylated styrene-butadiene copolymer.

5 . The composition according to claim 3 , wherein the polymer is a non-carboxylated styrene-butadiene copolymer.

6 . The composition according to claim 1 , wherein the polymer is further derived from glycidyl methacrylate or N-methylolacrylamide.

7 . The composition according to claim 1 , wherein the ionic cross-linking agent has a valency of at least 2.

8 . The composition according to claim 1 , wherein the ionic cross-linking agent has a valency of at least 3.

9 . The composition according to claim 1 , wherein the ionic crosslinking agent includes zirconium.

10 . The composition according to claim 1 , wherein the crosslinked product is free of sulfur.

11 . A paint, a paper binding or paper coating composition, an adhesive, a foam, a powder, or a carpet composition comprising the composition according to claim 1 .

12 . An asphalt composition comprising the composition according to claim 1 .

13 . The asphalt composition according to claim 12 , wherein the Strategic Highway Research Program (SHRP) fresh high temperature, Rolling Thin-Film Oven (RTFO) SHRP high temperature, or both of the asphalt composition is at least 1 PG (performance grade) improvement over an identical asphalt composition without the ionic crosslinking agent.

14 . A method of producing a crosslinked asphalt composition, comprising:
blending a polymer derived from styrene and optionally butadiene, an ionic crosslinking agent, and asphalt at a blending temperature of 5° C. to 200° C.; and crosslinking the asphalt with the ionic crosslinking agent to form a crosslinked asphalt composition.

15 . The method according to claim 14 , wherein the polymer is polystyrene.

16 . The method according to claim 14 , wherein the polymer is derived from styrene and butadiene.

17 . The method according to claim 14 , wherein the polymer is formed using emulsion polymerization.

18 . The method of claim 17 , wherein the emulsion polymerization is conducted at a temperature of 5° C. to 90° C.

19 . The method according to claim 14 , wherein the blending temperature is from 5° C. to 60° C.

20 . The method according to claim 14 , wherein the blending temperature is ambient temperature.
