Abstract
The present invention relates to a new type of polyolefin based hot-melt adhesive and methods for their production. More particularly, it relates to a new type of hot-melt adhesive comprising propylene co-polymers and possessing a favorable balance of cohesive strength, adhesion properties, and processibility, which render them especially well-suited for some hot-melt adhesive applications, for example, as elastic attachment adhesives.
Claims20
1) A composition of matter useful as an adhesive, which comprises:
- a) about 30% to about 90% by weight, based on the total weight of said composition, of a polypropylene component selected from the group consisting of:
- polypropylene homopolymers, polypropylene co-polymers, and any mixtures of the foregoing;
- b) about 10% to about 60% by weight, based on the total weight of said composition, of a tackifier resins component;
- c) about 0% to about 40% by weight, based on the total weight of said composition, of a functionalized polymer component;
- and
- d) about 0.01% to about 1% by weight, based on the total weight of said composition, of a stabilizer(s) component.
