Abstract

A process for producing rosin resins comprising reacting together rosin and phenolic compound and/or terpene-phenol resin, in the presence of a Brønsted acid. These resins may be used as tackifiers in adhesive formulations, including chloroprene contact cements.

Claims (19)

1. A process for producing a resin, comprising reacting rosin with a phenolic compound in the presence of a Bronsted acid under esterification reaction conditions to produce a rosin-phenol ester, wherein said rosin and said phenolic compound are reacted together in a rosin:phenolic compound weight ratio of from 70:30 to 90:10 wherein said esterification reaction conditions comprise the presence of a solvent.

2. The process according to claim 1 , wherein the rosin is at least one member selected from the group consisting of wood rosin, tall oil rosin, and gum rosin.

3. The process according to claim 1 , wherein rosin is reacted with phenol.

4. The process according to claim 1 , wherein rosin is reacted with alkylphenol.

5. The process according to claim 1 , wherein rosin is reacted with a C 1 -C 12 alkylphenol.

6. The process according to claim 1 , wherein the Bronsted acid is sulfonic acid, sulfuric acid, or mixture thereof.

7. The process according to claim 1 , wherein the Bronsted acid is paratoluene sulfonic acid, sulfonic acid, sulfuric acid, or mixtures thereof.

8. The process according to claim 1 , wherein the rosin is tall oil rosin.

9. The process according to claim 1 , wherein the rosin is gum rosin.

10. The process according to claim 9 , wherein the rosin is Chinese gum rosin.

11. A resin produced by the process according to claim 1 .

12. The resin according to claim 11 , wherein the resin has an acid number of from 30 to 85.

13. The resin according to claim 12 , wherein the resin has a Mw of from 550 to 1400.

14. The resin according to claim 13 , wherein the resin has a Mn of from 405 to 750.

15. The resin according to claim 14 , wherein the resin has a neat Gardner color of from 6 to 12.

16. The resin of claim 11 wherein the resin has a Mw of from 550 to 1400.

17. The resin of claim 11 wherein the resin has a Mn of from 405 to 750.

18. The resin of claim 11 wherein the resin has a neat Gardner color of from 6 to 12.

19. The resin of claim 11 wherein said resin has a softening point of from 115 to 150° C.
