Abstract

A hot melt adhesive comprising an adhesive polymer and a modified rosin-terpene, preferably a phenol modified rosin terpene. The adhesive is particularly useful in packaging applications.

Claims (20)

1. A hot melt adhesive comprising an adhesive polymer and a modified rosin-terpene, and having a viscosity of less than about 3000 cps at 150° C.

2. The adhesive of claim 1 wherein the modified rosin terpene is a phenolic modified rosin-terpene.

3. The adhesive of claim 2 wherein the phenol modified rosin-terpene has an average molecular weight to softening point ratio of less than about 10.

4. The adhesive of claim 2 wherein the phenol modified rosin-terpene has a Ring & Ball softening point of from about 125° C. to about 150° C.

5. The adhesive of claim 2 wherein the phenol modified rosin-terpene has an acid number of from about 25 to about 85.

6. The adhesive of claim 2 wherein the phenol modified rosin-terpene has a weight average molecular weight of 600 to 1000.

7. The adhesive of claim 1 further comprising a wax.

8. The adhesive of claim 7 wherein the wax is a paraffin, a microcrystalline wax or a blend thereof.

9. The adhesive of claim 1 wherein the adhesive polymer comprises at least one ethylene copolymer.

10. The adhesive of claim 9 comprising at least one ethylene n-butyl acrylate copolymer.

11. The adhesive of claim 10 further comprising ethylene vinyl acetate.

12. The adhesive of claim 1 comprising from about 10 to about 60% by weight of the modified rosin-terpene.

13. The adhesive of claim 1 which has a heat stress of equal to or greater than about 125° F.

14. The adhesive of claim 1 which has a viscosity of less than about 1300 cps at 250° F.

15. The adhesive of claim 1 which has a cloud point of less than about 220 F.

16. An article of manufacture comprising a hot melt adhesive wherein the adhesive contains an ethylene copolymer and a modified rosin-terpene.

17. A hot melt adhesive comprising an ethylene copolymer and a modified rosin-terpene.

18. The adhesive of claim 17 wherein the modified rosin-terpene is a phenolic modified rosin-terpene.

19. The adhesive of claim 17 wherein the ethylene copolymer is ethylene n-butyl acrylate and/or ethylene vinyl acetate.

20. The adhesive of claim 18 wherein the phenol modified rosin-terpene has an average molecular weight to softening point ratio of less than about 10.
