OLEFIN-BASED POLYMER AND PREPARATION METHOD THEREOF

摘要

The present invention relates to an olefin-based polymer which exhibits superior processability and superior adhesive properties and therefore is desirably applicable to a hot-melt adhesive (HMA) or the like, and a preparation method thereof. The olefin-based polymer has a molecular weight distribution (Mw/Mn, PDI) of 2˜3, and a density of 0.85 to 0.88 g/cm3, and satisfies the relation of Tc−Tm>0, wherein Tc (° C.) is a crystallization temperature and Tm (° C.) is a melting point.
