Polyolefin Adhesive Compositions for Elastic Applications

An article comprising a blend of

• (a) at least one propylene terpolymer comprising propylene derived units, one or more dienes, and one or more C2 or C4 to C20 alpha-olefins, where the C2 or C4 to C20 alpha-olefin content is less than about 35 wt % of the propylene terpolymer;
• and
• (b) an adhesive composition, comprising
• a polymer blend comprising a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin, and a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin;
• wherein the second propylene-based polymer is different than the first propylene-based polymer, and wherein the polymer blend is present in the amount of about 20 to about 80 wt % of the adhesive composition.

A method of applying an adhesive composition to a substrate, wherein the method comprises the steps of:

• (a) preparing a substrate, comprising
• at least one propylene terpolymer comprising propylene derived units, one or more dienes, and one or more C2 or C4 to C20 alpha-olefins, where the C2 or C4 to C20 alpha-olefin content is less than about 35 wt % of the propylene terpolymer;
• and
• (b) applying an adhesive composition to the substrate at a temperature of less than about 150° C.,
• wherein the adhesive composition comprises a polymer blend comprising a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin, and a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin;
• wherein the second propylene-based polymer is different than the first propylene-based polymer, and wherein the polymer blend is present in the amount of about 20 to about 80 wt % of the adhesive composition.
