Low application tempearature amorphous poly-α-olefin adhesive |
| 摘要 |
It has been discovered that amorphous polybutene copolymers that have a softening point of from about 70 to about 105° C. and viscosity of less than about 1,900 cP at 190° C. possesses desirable properties and may be used to make a low application temperature hot melt adhesive for disposable absorbent articles. |

1. A hot melt adhesive comprising at least 45 wt %, based on the adhesive, of an amorphous polybutene copolymer having (a) greater than about 50 wt % of 1-butene monomer, (b) a softening point of from about 70 to about 105° C. and (c) a viscosity of less than about 1,900 cP at 190° C., and (d) a tan δ value greater than 30 at 140° C.
wherein the hot melt adhesive has a viscosity of less than about 6,000 cP at 150° C. |
