Multi-modal polymer blend, hot melt adhesive comprising same and use thereof

A multi-modal polymer blend of at least three fractions as determined by Temperature Rising Elution Fractionation, said blend comprising:

• a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and at least one member selected from the group consisting of ethylene and a C4 to C20 alpha-olefin;
• a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and at least one member selected from the group consisting of ethylene and a C4 to C20 alpha-olefin;
• wherein the second propylene-based polymer is different than the first propylene-based polymer;
• and
• a third propylene-based polymer, wherein the third propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and at least one member selected from the group consisting of ethylene and a C4 to C20 alpha-olefin;
• wherein the third propylene-based polymer is different than the first propylene-based polymer and the second propylene-based polymer;
• wherein the multi-modal polymer blend has a Mw of about 5000 g/mol to about 250,000 g/mol;
• and
• wherein, when subjected to Temperature Rising Elution Fractionation, the multi-modal polymer blend exhibits:
• a first fraction that is soluble at −15° C. in xylene, the first fraction having an isotactic (mm) triad tacticity of about 55 mol % to about 85 mol %;
• a second fraction that is insoluble at −5° C. in xylene or dichlorobenzene and soluble at 40° C. in xylene or dichlorobenzene, and
• a third fraction that is insoluble at 70° C. in xylene or dichlorobenzene, the third fraction having an isotactic (mm) triad tacticity of about 85 mol % to about 98 mol %.
