Abstract

The present invention refers to a resin composition comprising an ester compound and a polymer, wherein the ester compound and the polymer are obtainable by reacting a diene, a dienophile and a carboxylic acid. The invention also refers to adhesive compositions comprising the resin composition.

Claims (17)

1. A resin composition comprising a polymer and at least 5% by weight of an ester compound, wherein the ester compound and the polymer are obtained by reacting a diene, a dienophile and a rosin acid in the presence of a disproportionation agent, wherein the dienophile is an aromatic vinylic hydrocarbon.

2. A resin composition according to claim 1 comprising at least 10% by weight of the ester compound.

3. A resin composition according to claim 1 , wherein the polymer has no acid functionalities.

4. A resin composition according to claim 1 , wherein the ester compound and the polymer are obtained from a reaction mixture, comprising up to 75% by weight of the diene, up to 55% by weight of the dienophile, and from about 10 to about 75% by weight of the rosin acid.

5. A resin composition according to claim 4 , wherein the reaction mixture comprises from about 15 to about 60% by weight of the diene, from about 10 to about 45% by weight of the dienophile, and from about 15 to about 60% by weight of the carboxylic acid.

6. A resin composition according to claim 1 , wherein the resin composition has an acid number below 50.

7. A resin composition according to claim 1 , wherein the resin composition has an acid number below 20.

8. A resin composition according to claim 1 , wherein the diene is a hydrocarbon diene.

9. A resin composition according to claim 8 , wherein the diene is a cyclic hydrocarbon diene.

10. A resin composition according to claim 9 , wherein the diene is a polycyclic hydrocarbon diene.

11. A resin composition according to claim 10 , wherein the diene is dicyclopentadiene.

12. A resin composition according to claim 1 , wherein the dienophile is styrene.

13. A resin composition comprising a polymer and at least 5% by weight of an ester compound, wherein the ester compound and the polymer are obtained by reacting a polycyclic hydrocarbon diene, a dienophile and a rosin acid or a mixture of rosin acids in the presence of a disproportionation agent, wherein the dienophile is an aromatic vinylic hydrocarbon, and wherein the resin composition has an acid number below 50.

14. A resin composition according to claim 13 , wherein the ester compound and the polymer are obtained by reacting up to 75% by weight of the diene, up to 55% by weight of the dienophile, and from 10 up to 75% by weight of the rosin acid or the mixture thereof.

15. A resin composition comprising at least 5% by weight of an ester compound, and a polymer, wherein the ester compound and the polymer are obtained by reacting a polycyclic hydrocarbon diene, styrene and a rosin acid or a mixture of rosin acids in the presence of a disproportionation agent.

16. A method for producing a resin composition which comprises providing a reaction mixture comprising up to 75% by weight of a diene, up to 55% by weight of a dienophile, wherein the dienophile is an aromatic vinylic hydrocarbon, and from about 10 to about 75% by weight of a rosin acid in the presence of a disproportionation agent, heating the reaction mixture at a temperature from about 175° C. up to 310° C. for about 1 up to 2 hours.

17. A method for producing a resin composition according to claim 16 , wherein the reaction mixture comprises from about 15 to about 60% by weight of a diene, from about 10 to about 45% by weight of a dienophile, and from about 15 to about 60% by weight of a rosin acid.
