We claim: 1. A method for producing an adhesive composition consisting of: a vinyl acetate-ethylene copolymer; an alkali swellable thickener; water; and a source of alkalinity; wherein the vinyl acetate-ethylene copolymer is dispersed within the water and the adhesive composition has a pH of 4 to 1
We claim: 1. A method for producing an adhesive composition consisting of: a vinyl acetate-ethylene copolymer; an alkali swellable thickener; water; and a source of alkalinity; wherein the vinyl acetate-ethylene copolymer is dispersed within the water and the adhesive composition has a pH of 4 to 10; and wherein the adhesive composition has a stringing length of 9 cm or less, a set time of 180 seconds or less, and one or more of the following properties: a phase lag of 45 degrees or less; a viscosity of 3,000 to 50,000 cP; a complex shear modulus of 50 to 1000 Pa; and a sag distance of 10 mm or less. 2. The method of claim 1, wherein the vinyl acetate-ethylene copolymer is present in the adhesive composition at 5 to 75 wt % and the alkali swellable thickener is present in the adhesive composition at 0.1 to 10 wt %. 3. The method of claim 2, wherein the vinyl acetate-ethylene copolymer is present in the adhesive composition at 20 to 75 wt % and the alkali swellable thickener is present in the adhesive composition at 0.1 to 5 wt %. 4. The method of claim 2, wherein the vinyl acetate-ethylene copolymer is present in the adhesive composition at 50 to 75 wt % and the alkali swellable thickener is present in the adhesive composition at 0.1 to 3 wt %. 5.

The method of claim 1, wherein the adhesive composition has a total solids content of 5 to 85%. 8. The method of claim 7, wherein the adhesive composition has a total solids content of 30 to 85%. 9. The method of claim 7, the adhesive composition has a total solids content of 60 to 80%. 10. The method of claim 1, wherein the adhesive composition has a phase lag of 30 degrees or less. 11. The method of claim 10, wherein the adhesive composition has a sag distance of 5 mm or less. 12. The method of claim 10, wherein the adhesive composition has a sag distance of 2 mm or less. 13. The method of claim 1, wherein the adhesive composition has a viscosity of 3,000 to 30,000 cP. 14. The method of claim 13, wherein the adhesive composition has a viscosity of 10,000 to 30,000 cP. 15. The method of claim 1, wherein the adhesive composition has a set time 60 seconds or less. 16. The method of claim 1, wherein the adhesive composition has a complex shear modulus of 100 to 600 Pa. 17. The method of claim 1, wherein the adhesive composition has a stringing length of 5 cm or less. 18. The method of claim 17, wherein the adhesive composition has a stringing length of 3 cm or less. 19. A method of bonding a first adherent to a second adherent, comprising: applying an adhesive composition to the first adherent; and placing the second adherent in contact with the adhesive composition, wherein the adhesive composition being produced by the method of claim 1.
