POLYOLEFIN ADHESIVE COMPOSITIONS AND METHODS OF PREPARING THE SAME |
摘要 |
A multi-modal polymer blend for use in an adhesive composition comprising at least two compositionally different propylene-based polymers. The multi-modal polymer blend has a Mw of about 10,000 g/mol to about 150,000 g/mol. When subjected to Temperature Rising Elution Fractionation, the multi-modal polymer blend exhibits a first fraction that is soluble at −15° C. in a hydrocarbon solvent, such as xylene or ortho-dichlorobenzene, the first fraction having an isotactic (mm) triad tacticity of about 70 mol % to about 90 mol %; and a second fraction that is insoluble or less soluble than the first fraction at −15° C. in the hydrocarbon solvent, the second fraction having an isotactic (mm) triad tacticity of about 85 mol % to about 98 mol %. |
