  • Multi-modal polymer blend, hot melt adhesive comprising same and use thereof
    Patent number: 10294357
    Abstract: A multi-modal polymer blend of at least three fractions as determined by TREF is provided. The blend comprises a first propylene-based polymer, a second propylene-based polymer; and a third propylene-based polymer; wherein when subjected to TREF, the 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 and having an isotactic (mm) triad tacticity of about 85 mol % to about 98 mol %. Also provided are hot melt adhesive compositions comprising the polymer blend, tackifier, wax; and optionally a nucleating agent, articles containing the adhesive and methods of fabricating the articles.
