Abstract
An olefin polymer and a preparation method for manufacturing the olefin polymer are disclosed. The olefin polymer has a high melting point and a high crystallization temperature, thus having excellent heat resistance. Therefore, the olefin polymer may be utilized in spout pouches for high-temperature liquid containers, or the like. The olefin polymer may have a density of 0.9 to 0.95 g/cm3, preferably 0.91 to 0.945 g/cm3, and satisfies the following Equations 1a and 2a: 224.02×d−86.257<Tm, and [Equation 1a] 219.64×d−95.767<Tc. [Equation 2a]
Claims17
An olefinic polymer that has a density of 0.9 to 0.95 g/cm3 and satisfies the following Equations 1a and 2a:
- 224.02×d−86.257<Tm [Equation 1]
- 219.64×d−95.767<Tc [Equation 2a]
- wherein Tm is a melting temperature (° C.), Tc is a crystallization temperature (° C.), and d is a density (g/cm3) of the olefinic polymer.
