Claims
- 1. A hot-melt adhesive comprising from 45-95% by weight of a vinyl polymer comprising:
- (a) 40-90% by weight of a C.sub.1 -C.sub.12 alkyl acrylate, and 10-60% by weight of an alpha-olefin of C.sub.20 -C.sub.40,
- wherein said alkyl acrylate is partially replaced with up to 60% by weight, based on the polymer, of vinyl acetate or with up to 10% by weight, based on the polymer, of a C.sub.6 -C.sub.12 olefin or with a mixture of vinyl acetate and C.sub.6 -C.sub.12 olefin, provided that the polymer in all instances contains at least 10% by weight of said alkyl acrylate, and
- (b) 5-25% by weight of a tackifying resin, and
- (c) 0-30% by weight of a modifying component.
- 2. The hot-melt adhesive of claim 1 wherein said modifying component is a stabilizer, pigment, wax, or oil, of any mixture thereof.
- 3. The hot-melt adhesive of claim 1 wherein said alpha-olefin is present in an amount of 20-45% by weight of the polymer.
- 4. The hot-melt adhesive of claim 1 wherein said alpha-olefin is of C.sub.20 -C.sub.30.
- 5. The hot-melt adhesive of claim 1 wherein said adhesive comprises 10-30% by weight of said alkyl acrylate, 30-60% by weight of said vinyl acetate and 10-60% by weight of said alpha-olefin.
- 6. The hot-melt adhesive of claim 1 wherein said alkyl acrylate is ethyl or butyl acrylate.
- 7. The hot-melt adhesive of claim 1 wherein said tackifying resin is selected from the group consisting of rosin and modified rosins, aromatic hydrocarbon resins, coumarone-indene resins, aliphatic and aromatic-aliphatic copolymer resins and hydrogenated resins thereof, petroleum oils, phenolic resins, terpene resins and modified terpene resins.
- 8. A hot-melt adhesive comprising from 45-95% by weight of a vinyl polymer comprising:
- (a) 40-90% by weight of a C.sub.1 -C.sub.12 alkyl acrylate, and 10-60% by weight of an alpha-olefin of C.sub.20 -C.sub.40, and
- (b) 5-25% by weight of a tackifying resin, and
- (c) 0-30% by weight of a modifying component.
- 9. The hot-melt adhesive of claim 8 wherein said alpha-olefin is present in an amount of 20-45% by weight of the polymer and is of C.sub.20 -C.sub.30.
- 10. The hot-melt adhesive of claim 8 wherein said modifying component is a stabilizer, pigment, wax, or oil, or any mixture thereof.
- 11. The hot-melt adhesive of claim 8 wherein said tackifying resin is selected from the group consisting of rosin and modified rosins, aromatic hydrocarbon resins, coumarone-indene resins, aliphatic and aromatic-aliphatic copolymer resins and hydrogenated resins thereof, petroleum oils, phenolic resins, terpene resins and modified terpene resins.
- 12. The hot-melt adhesive of claim 8 wherein said alkyl acrylate is ethyl or butyl acrylate.
